21771-80-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21771-80-2 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 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21771-80:
(7*2)+(6*1)+(5*7)+(4*7)+(3*1)+(2*8)+(1*0)=102
102 % 10 = 2
So 21771-80-2 is a valid CAS Registry Number.
