Check Digit Verification of cas no

The CAS Registry Mumber 159-21-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 159-21:
(5*1)+(4*5)+(3*9)+(2*2)+(1*1)=57
57 % 10 = 7
So 159-21-7 is a valid CAS Registry Number.
