Check Digit Verification of cas no
The CAS Registry Mumber 881663-31-6 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 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 881663-31:
(8*8)+(7*8)+(6*1)+(5*6)+(4*6)+(3*3)+(2*3)+(1*1)=196
196 % 10 = 6
So 881663-31-6 is a valid CAS Registry Number.
