344335-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344335-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,3 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 344335-56:
(8*3)+(7*4)+(6*4)+(5*3)+(4*3)+(3*5)+(2*5)+(1*6)=134
134 % 10 = 4
So 344335-56-4 is a valid CAS Registry Number.
