Check Digit Verification of cas no
The CAS Registry Mumber 149-46-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 149-46:
(5*1)+(4*4)+(3*9)+(2*4)+(1*6)=62
62 % 10 = 2
So 149-46-2 is a valid CAS Registry Number.
