Check Digit Verification of cas no
The CAS Registry Mumber 344-19-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 344-19:
(5*3)+(4*4)+(3*4)+(2*1)+(1*9)=54
54 % 10 = 4
So 344-19-4 is a valid CAS Registry Number.

Urones, Beatriz,Martinez, Angel Manu,Rodriguez, Nuria,Arrayas, Ramon Gomez,Carretero, Juan C.
, p. 11044 - 11046 (2013/11/19)
A practical Cu-catalyzed direct ortho-halogenation of anilines under aerobic conditions has been developed. The reaction shows typically excellent mono-substitution selectivity, high ortho-regiocontrol and large functional group tolerance.
