Check Digit Verification of cas no

The CAS Registry Mumber 380383-84-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,0,3,8 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 380383-84:
(8*3)+(7*8)+(6*0)+(5*3)+(4*8)+(3*3)+(2*8)+(1*4)=156
156 % 10 = 6
So 380383-84-6 is a valid CAS Registry Number.

Synthesis of N-aryl hydrazides by copper-catalyzed coupling of hydrazides with aryl iodides.

Wolter,Klapars,Buchwald

, p. 3803 - 3805 (2001)

[reaction--see text] A convenient method for intermolecular N-arylation of hydrazides with substituted aryl iodides in the presence of a copper catalyst and Cs(2)CO(3) is reported. The C-N coupling of N-Boc hydrazine with para- and meta-substituted aryl iodides afforded the N-arylated products A, regioselectively. A reversal in regioselectivity is observed for the arylation of benzoic hydrazide with ortho-substituted aryl iodides, providing the N'-arylated products B.
