Check Digit Verification of cas no

The CAS Registry Mumber 7237-44-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,3 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7237-44:
(6*7)+(5*2)+(4*3)+(3*7)+(2*4)+(1*4)=97
97 % 10 = 7
So 7237-44-7 is a valid CAS Registry Number.
