34403-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34403-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,0 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34403-74:
(7*3)+(6*4)+(5*4)+(4*0)+(3*3)+(2*7)+(1*4)=92
92 % 10 = 2
So 34403-74-2 is a valid CAS Registry Number.
