Check Digit Verification of cas no

The CAS Registry Mumber 1219799-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,7,9 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1219799-83:
(9*1)+(8*2)+(7*1)+(6*9)+(5*7)+(4*9)+(3*9)+(2*8)+(1*3)=203
203 % 10 = 3
So 1219799-83-3 is a valid CAS Registry Number.
