Check Digit Verification of cas no

The CAS Registry Mumber 223638-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,6,3 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 223638-13:
(8*2)+(7*2)+(6*3)+(5*6)+(4*3)+(3*8)+(2*1)+(1*3)=119
119 % 10 = 9
So 223638-13-9 is a valid CAS Registry Number.
