Check Digit Verification of cas no

The CAS Registry Mumber 3737-41-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3737-41:
(6*3)+(5*7)+(4*3)+(3*7)+(2*4)+(1*1)=95
95 % 10 = 5
So 3737-41-5 is a valid CAS Registry Number.
