Check Digit Verification of cas no
The CAS Registry Mumber 63131-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,1,3 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63131-33:
(7*6)+(6*3)+(5*1)+(4*3)+(3*1)+(2*3)+(1*3)=89
89 % 10 = 9
So 63131-33-9 is a valid CAS Registry Number.
