Check Digit Verification of cas no

The CAS Registry Mumber 63833-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,3 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63833-46:
(7*6)+(6*3)+(5*8)+(4*3)+(3*3)+(2*4)+(1*6)=135
135 % 10 = 5
So 63833-46-5 is a valid CAS Registry Number.
