Check Digit Verification of cas no

The CAS Registry Mumber 917201-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,0 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 917201-76:
(8*9)+(7*1)+(6*7)+(5*2)+(4*0)+(3*1)+(2*7)+(1*6)=154
154 % 10 = 4
So 917201-76-4 is a valid CAS Registry Number.
