40341-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40341-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,4 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40341-68:
(7*4)+(6*0)+(5*3)+(4*4)+(3*1)+(2*6)+(1*8)=82
82 % 10 = 2
So 40341-68-2 is a valid CAS Registry Number.
