Check Digit Verification of cas no

The CAS Registry Mumber 132990-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,9 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132990-36:
(8*1)+(7*3)+(6*2)+(5*9)+(4*9)+(3*0)+(2*3)+(1*6)=134
134 % 10 = 4
So 132990-36-4 is a valid CAS Registry Number.
