Check Digit Verification of cas no

The CAS Registry Mumber 6744-88-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6744-88:
(6*6)+(5*7)+(4*4)+(3*4)+(2*8)+(1*8)=123
123 % 10 = 3
So 6744-88-3 is a valid CAS Registry Number.
