Check Digit Verification of cas no

The CAS Registry Mumber 1156538-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,6,5,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1156538-63:
(9*1)+(8*1)+(7*5)+(6*6)+(5*5)+(4*3)+(3*8)+(2*6)+(1*3)=164
164 % 10 = 4
So 1156538-63-4 is a valid CAS Registry Number.
