234444-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 234444-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,4,4,4 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 234444-34:
(8*2)+(7*3)+(6*4)+(5*4)+(4*4)+(3*4)+(2*3)+(1*4)=119
119 % 10 = 9
So 234444-34-9 is a valid CAS Registry Number.
