Check Digit Verification of cas no

The CAS Registry Mumber 2037-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,3 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2037-17:
(6*2)+(5*0)+(4*3)+(3*7)+(2*1)+(1*7)=54
54 % 10 = 4
So 2037-17-4 is a valid CAS Registry Number.
