Check Digit Verification of cas no

The CAS Registry Mumber 21022-29-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,2 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21022-29:
(7*2)+(6*1)+(5*0)+(4*2)+(3*2)+(2*2)+(1*9)=47
47 % 10 = 7
So 21022-29-7 is a valid CAS Registry Number.
