Check Digit Verification of cas no

The CAS Registry Mumber 21743-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,4 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21743-49:
(7*2)+(6*1)+(5*7)+(4*4)+(3*3)+(2*4)+(1*9)=97
97 % 10 = 7
So 21743-49-7 is a valid CAS Registry Number.
