34144-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34144-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,4 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34144-30:
(7*3)+(6*4)+(5*1)+(4*4)+(3*4)+(2*3)+(1*0)=84
84 % 10 = 4
So 34144-30-4 is a valid CAS Registry Number.
