Check Digit Verification of cas no

The CAS Registry Mumber 2371-07-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,7 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2371-07:
(6*2)+(5*3)+(4*7)+(3*1)+(2*0)+(1*7)=65
65 % 10 = 5
So 2371-07-5 is a valid CAS Registry Number.
