Check Digit Verification of cas no
The CAS Registry Mumber 91-96-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91-96:
(4*9)+(3*1)+(2*9)+(1*6)=63
63 % 10 = 3
So 91-96-3 is a valid CAS Registry Number.
