Check Digit Verification of cas no

The CAS Registry Mumber 1566557-16-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,6,5,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1566557-16:
(9*1)+(8*5)+(7*6)+(6*6)+(5*5)+(4*5)+(3*7)+(2*1)+(1*6)=201
