Check Digit Verification of cas no

The CAS Registry Mumber 137469-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,6 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137469-63:
(8*1)+(7*3)+(6*7)+(5*4)+(4*6)+(3*9)+(2*6)+(1*3)=157
157 % 10 = 7
