Check Digit Verification of cas no

The CAS Registry Mumber 4762-76-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,6 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4762-76:
(6*4)+(5*7)+(4*6)+(3*2)+(2*7)+(1*6)=109
109 % 10 = 9
So 4762-76-9 is a valid CAS Registry Number.
