Check Digit Verification of cas no

The CAS Registry Mumber 123729-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,2 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123729-87:
(8*1)+(7*2)+(6*3)+(5*7)+(4*2)+(3*9)+(2*8)+(1*7)=133
133 % 10 = 3
So 123729-87-3 is a valid CAS Registry Number.
