Check Digit Verification of cas no

The CAS Registry Mumber 1616975-19-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,9,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1616975-19:
(9*1)+(8*6)+(7*1)+(6*6)+(5*9)+(4*7)+(3*5)+(2*1)+(1*9)=199
199 % 10 = 9
So 1616975-19-9 is a valid CAS Registry Number.
