Check Digit Verification of cas no
The CAS Registry Mumber 136663-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,6 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136663-21:
(8*1)+(7*3)+(6*6)+(5*6)+(4*6)+(3*3)+(2*2)+(1*1)=133
133 % 10 = 3
So 136663-21-3 is a valid CAS Registry Number.
