129228-61-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129228-61-1 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 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129228-61:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*8)+(2*6)+(1*1)=131
131 % 10 = 1
So 129228-61-1 is a valid CAS Registry Number.
