34413-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34413-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,1 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34413-12:
(7*3)+(6*4)+(5*4)+(4*1)+(3*3)+(2*1)+(1*2)=82
82 % 10 = 2
So 34413-12-2 is a valid CAS Registry Number.
