Check Digit Verification of cas no

The CAS Registry Mumber 3771-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,7 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3771-62:
(6*3)+(5*7)+(4*7)+(3*1)+(2*6)+(1*2)=98
98 % 10 = 8
So 3771-62-8 is a valid CAS Registry Number.
