Check Digit Verification of cas no

The CAS Registry Mumber 1447924-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,9,2 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1447924-99:
(9*1)+(8*4)+(7*4)+(6*7)+(5*9)+(4*2)+(3*4)+(2*9)+(1*9)=203
203 % 10 = 3
So 1447924-99-3 is a valid CAS Registry Number.
