Check Digit Verification of cas no

The CAS Registry Mumber 501691-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,6,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 501691-17:
(8*5)+(7*0)+(6*1)+(5*6)+(4*9)+(3*1)+(2*1)+(1*7)=124
124 % 10 = 4
So 501691-17-4 is a valid CAS Registry Number.
