Check Digit Verification of cas no
The CAS Registry Mumber 129-09-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129-09:
(5*1)+(4*2)+(3*9)+(2*0)+(1*9)=49
49 % 10 = 9
So 129-09-9 is a valid CAS Registry Number.
