Check Digit Verification of cas no

The CAS Registry Mumber 132-88-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132-88:
(5*1)+(4*3)+(3*2)+(2*8)+(1*8)=47
47 % 10 = 7
So 132-88-7 is a valid CAS Registry Number.
