344261-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344261-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,2,6 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 344261-34:
(8*3)+(7*4)+(6*4)+(5*2)+(4*6)+(3*1)+(2*3)+(1*4)=123
123 % 10 = 3
So 344261-34-3 is a valid CAS Registry Number.
