74536-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74536-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,3 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74536-64:
(7*7)+(6*4)+(5*5)+(4*3)+(3*6)+(2*6)+(1*4)=144
144 % 10 = 4
So 74536-64-4 is a valid CAS Registry Number.
