129129-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129129-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,2 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129129-56:
(8*1)+(7*2)+(6*9)+(5*1)+(4*2)+(3*9)+(2*5)+(1*6)=132
132 % 10 = 2
So 129129-56-2 is a valid CAS Registry Number.
