81919-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81919-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,1 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81919-21:
(7*8)+(6*1)+(5*9)+(4*1)+(3*9)+(2*2)+(1*1)=143
143 % 10 = 3
So 81919-21-3 is a valid CAS Registry Number.
