Check Digit Verification of cas no

The CAS Registry Mumber 26244-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 26244-33:
(7*2)+(6*6)+(5*2)+(4*4)+(3*4)+(2*3)+(1*3)=97
97 % 10 = 7
So 26244-33-7 is a valid CAS Registry Number.
