344738-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344738-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,7,3 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344738-48:
(8*3)+(7*4)+(6*4)+(5*7)+(4*3)+(3*8)+(2*4)+(1*8)=163
163 % 10 = 3
So 344738-48-3 is a valid CAS Registry Number.
