343256-46-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343256-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,2,5 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 343256-46:
(8*3)+(7*4)+(6*3)+(5*2)+(4*5)+(3*6)+(2*4)+(1*6)=132
132 % 10 = 2
So 343256-46-2 is a valid CAS Registry Number.
