Check Digit Verification of cas no

The CAS Registry Mumber 1242069-49-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,6 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1242069-49:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*6)+(3*9)+(2*4)+(1*9)=133
133 % 10 = 3
So 1242069-49-3 is a valid CAS Registry Number.
