Check Digit Verification of cas no
The CAS Registry Mumber 881919-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,9,1 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 881919-82:
(8*8)+(7*8)+(6*1)+(5*9)+(4*1)+(3*9)+(2*8)+(1*2)=220
220 % 10 = 0
So 881919-82-0 is a valid CAS Registry Number.
