21772-12-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21772-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,7 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21772-12:
(7*2)+(6*1)+(5*7)+(4*7)+(3*2)+(2*1)+(1*2)=93
93 % 10 = 3
So 21772-12-3 is a valid CAS Registry Number.
