Check Digit Verification of cas no

The CAS Registry Mumber 5345-77-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5345-77:
(6*5)+(5*3)+(4*4)+(3*5)+(2*7)+(1*7)=97
97 % 10 = 7
So 5345-77-7 is a valid CAS Registry Number.
