IC pins are numbered anti-clockwise around the IC starting near the notch or dot.
read the datasheet or databook entry for the chip. there is no other reliable way.

You can just Google the IC number and check the datasheet. This is very useful for getting the pin configuration of other IC as well. Anyway 7486 is a 14pins, 4 independence gates of XOR Gate Input Output #1 Pin1 Pin2 PIN3 #2 Pin4 Pin5 PIN6 #3 Pin10Pin9 Pin8 #4 Pin13Pin12 Pin11 Others Vcc Pin 14 Gnd Pin 7 Hope that helps.
8-pin 555 timer IC
a tab on a metal case or a dot on a molded plastic case is typical.
you start from the notch of the I.C and then you go anti clockwise making the pin at the bottom of the notch 1 and the pin above the notch 14 .
It is a personal number used to identify a bank account, and is to be kept extremely secret. Most IC will have a dot or a mark or a tag TO IDENTIFY the pin 1 from the top pin 2 will be considered to be on your right sequentially clockwise
Simple case: First pin to the LEFT of a dot and/or a notch is pin 1. Chip with > 1 dot: The darker/deeper dot is the main dot, first pin to the left is pin 1. No dot or notch, just a semi circle on 1 side: First pin on the left is pin 1.

The 8085 is a 40 pin ic because Intel designed it that way.
um66 is a melody generator cmos ic it is a three terminal ic pin no: 1 is set to ground, and pin 2 is Vdd pin 3 is the output melody signal this ic generally operates from 1.5 to 5 volts it is generally used in toys, bells etc................
IC 7402 is different from the other type of IC like 7404,7408,7432 and 7400 when it is connected to have an output desired... if you noticed all i mentioned ic is connected from left to the right. input pin 1 and 2, output pin 3 input pin 4 and 5, output pin 6 input pin 13 and 12, output pin 11 input pin 10 and 9, output pin 8 while in nor gate, to have the desired output it must be connected from right to left... input pin 2 and 3, output pin 1 input pin 5 and 6, output pin 4 input pin 8 and 9, output pin 10 input pin 11 and 12, output pin 13
