Check Digit Verification of cas no

The CAS Registry Mumber 3769-85-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,6 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3769-85:
(6*3)+(5*7)+(4*6)+(3*9)+(2*8)+(1*5)=125
125 % 10 = 5
So 3769-85-5 is a valid CAS Registry Number.
