344338-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344338-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 344338-98:
(8*3)+(7*4)+(6*4)+(5*3)+(4*3)+(3*8)+(2*9)+(1*8)=153
153 % 10 = 3
So 344338-98-3 is a valid CAS Registry Number.
