Check Digit Verification of cas no

The CAS Registry Mumber 6709-29-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6709-29:
(6*6)+(5*7)+(4*0)+(3*9)+(2*2)+(1*9)=111
111 % 10 = 1
So 6709-29-1 is a valid CAS Registry Number.
