129155-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129155-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,5 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129155-31:
(8*1)+(7*2)+(6*9)+(5*1)+(4*5)+(3*5)+(2*3)+(1*1)=123
123 % 10 = 3
So 129155-31-3 is a valid CAS Registry Number.
