Check Digit Verification of cas no

The CAS Registry Mumber 819793-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,9,7,9 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 819793-52:
(8*8)+(7*1)+(6*9)+(5*7)+(4*9)+(3*3)+(2*5)+(1*2)=217
217 % 10 = 7
