Check Digit Verification of cas no
The CAS Registry Mumber 69521-64-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,2 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69521-64:
(7*6)+(6*9)+(5*5)+(4*2)+(3*1)+(2*6)+(1*4)=148
148 % 10 = 8
So 69521-64-8 is a valid CAS Registry Number.
