129226-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129226-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,2 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129226-99:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*6)+(2*9)+(1*9)=139
139 % 10 = 9
So 129226-99-9 is a valid CAS Registry Number.
