Check Digit Verification of cas no

The CAS Registry Mumber 137109-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,0 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137109-46:
(8*1)+(7*3)+(6*7)+(5*1)+(4*0)+(3*9)+(2*4)+(1*6)=117
117 % 10 = 7
So 137109-46-7 is a valid CAS Registry Number.
