74121-11-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74121-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,2 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74121-11:
(7*7)+(6*4)+(5*1)+(4*2)+(3*1)+(2*1)+(1*1)=92
92 % 10 = 2
So 74121-11-2 is a valid CAS Registry Number.
