Check Digit Verification of cas no

The CAS Registry Mumber 4771-23-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4771-23:
(6*4)+(5*7)+(4*7)+(3*1)+(2*2)+(1*3)=97
97 % 10 = 7
So 4771-23-7 is a valid CAS Registry Number.
