Check Digit Verification of cas no

The CAS Registry Mumber 5651-59-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5651-59:
(6*5)+(5*6)+(4*5)+(3*1)+(2*5)+(1*9)=102
102 % 10 = 2
So 5651-59-2 is a valid CAS Registry Number.
