Check Digit Verification of cas no

The CAS Registry Mumber 1229-09-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229-09:
(6*1)+(5*2)+(4*2)+(3*9)+(2*0)+(1*9)=60
60 % 10 = 0
So 1229-09-0 is a valid CAS Registry Number.
