344559-44-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344559-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,5,5 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 344559-44:
(8*3)+(7*4)+(6*4)+(5*5)+(4*5)+(3*9)+(2*4)+(1*4)=160
160 % 10 = 0
So 344559-44-0 is a valid CAS Registry Number.
