Check Digit Verification of cas no

The CAS Registry Mumber 101937-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,9,3 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 101937-13:
(8*1)+(7*0)+(6*1)+(5*9)+(4*3)+(3*7)+(2*1)+(1*3)=97
97 % 10 = 7
