Check Digit Verification of cas no

The CAS Registry Mumber 7497-35-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7497-35:
(6*7)+(5*4)+(4*9)+(3*7)+(2*3)+(1*5)=130
130 % 10 = 0
So 7497-35-0 is a valid CAS Registry Number.

4,6-Dimethylpyridine-2,3-dicarbonitrile and its reaction with N-acylhydrazines

Rudenko,Kucherak,Tolmachev,Hordiyenko

, p. 964 - 969 (2012/03/26)

An efficient method has been developed for the synthesis of 4,6-dimethylpyridine-2,3-dicarbonitrile. A study was carried out on the reaction of this compound with N-acylhydrazines to give two structural isomers, namely, N′-(7-amino-2,4-dimethyl-5H-pyrrolo[3,4-b]pyridin-5-ylidene) carbohydrazides and N′-(5-amino-2,4-dimethyl-7H-pyrrolo[3,4-b]pyridin-7- ylidene)carbohydrazides as well as disubstituted N′,N″-(2,4- dimethyl-5H-pyrrolo[3,4-b]pyridine-5,7-diylidene)dicarbohydrazides.

Magnesiation of pyridine N-oxides via iodine or bromine-magnesium exchange: A useful tool for functionalizing pyridine N-oxides

Duan, Xin-Fang,Zi-Qian, Ma.,Zhang, Fang,Zhang, Zhan-Bin

supporting information; experimental part, p. 939 - 942 (2009/06/20)

Iodo- or 2-bromopyridine N-oxides were readily magnesiated with i-PrMgCl ? LiCl via the iodine or bromine-magnesium exchange. The bromine adjacent to pyridine N-oxide (at the 2- or 6-position) can be regioselectively magnesiated in the presence of other position substituted halogens. This method was tested in various substituted pyridine N-oxide systems, and has been successfully applied to the total synthesis of caerulomycins E and A.
