Check Digit Verification of cas no

The CAS Registry Mumber 1337987-45-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,9,8 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1337987-45:
(9*1)+(8*3)+(7*3)+(6*7)+(5*9)+(4*8)+(3*7)+(2*4)+(1*5)=207
207 % 10 = 7
So 1337987-45-7 is a valid CAS Registry Number.
