129256-81-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129256-81-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,5 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129256-81:
(8*1)+(7*2)+(6*9)+(5*2)+(4*5)+(3*6)+(2*8)+(1*1)=141
141 % 10 = 1
So 129256-81-1 is a valid CAS Registry Number.
