Check Digit Verification of cas no

The CAS Registry Mumber 130633-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,3 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130633-22:
(8*1)+(7*3)+(6*0)+(5*6)+(4*3)+(3*3)+(2*2)+(1*2)=86
86 % 10 = 6
So 130633-22-6 is a valid CAS Registry Number.
