Check Digit Verification of cas no

The CAS Registry Mumber 76744-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,4 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76744-35:
(7*7)+(6*6)+(5*7)+(4*4)+(3*4)+(2*3)+(1*5)=159
159 % 10 = 9
So 76744-35-9 is a valid CAS Registry Number.
