Check Digit Verification of cas no

The CAS Registry Mumber 1303-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1303-37:
(6*1)+(5*3)+(4*0)+(3*3)+(2*3)+(1*7)=43
43 % 10 = 3
So 1303-37-3 is a valid CAS Registry Number.
