Check Digit Verification of cas no

The CAS Registry Mumber 1141744-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,7,4 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1141744-75:
(9*1)+(8*1)+(7*4)+(6*1)+(5*7)+(4*4)+(3*4)+(2*7)+(1*5)=133
133 % 10 = 3
So 1141744-75-3 is a valid CAS Registry Number.
