Check Digit Verification of cas no

The CAS Registry Mumber 1609563-29-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,5,6 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1609563-29:
(9*1)+(8*6)+(7*0)+(6*9)+(5*5)+(4*6)+(3*3)+(2*2)+(1*9)=182
182 % 10 = 2
So 1609563-29-2 is a valid CAS Registry Number.
