143914-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143914-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,1 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143914-65:
(8*1)+(7*4)+(6*3)+(5*9)+(4*1)+(3*4)+(2*6)+(1*5)=132
132 % 10 = 2
So 143914-65-2 is a valid CAS Registry Number.
