129111-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129111-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,1 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129111-81:
(8*1)+(7*2)+(6*9)+(5*1)+(4*1)+(3*1)+(2*8)+(1*1)=105
105 % 10 = 5
So 129111-81-5 is a valid CAS Registry Number.
