Check Digit Verification of cas no
The CAS Registry Mumber 881668-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,6,6 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 881668-83:
(8*8)+(7*8)+(6*1)+(5*6)+(4*6)+(3*8)+(2*8)+(1*3)=223
223 % 10 = 3
So 881668-83-3 is a valid CAS Registry Number.
