Check Digit Verification of cas no

The CAS Registry Mumber 2239-53-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,3 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2239-53:
(6*2)+(5*2)+(4*3)+(3*9)+(2*5)+(1*3)=74
74 % 10 = 4
So 2239-53-4 is a valid CAS Registry Number.
