Check Digit Verification of cas no

The CAS Registry Mumber 20638-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20638-49:
(7*2)+(6*0)+(5*6)+(4*3)+(3*8)+(2*4)+(1*9)=97
97 % 10 = 7
So 20638-49-7 is a valid CAS Registry Number.
