Check Digit Verification of cas no

The CAS Registry Mumber 733744-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,3,7,4 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 733744-38:
(8*7)+(7*3)+(6*3)+(5*7)+(4*4)+(3*4)+(2*3)+(1*8)=172
172 % 10 = 2
So 733744-38-2 is a valid CAS Registry Number.
