Check Digit Verification of cas no

The CAS Registry Mumber 52809-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52809-72:
(7*5)+(6*2)+(5*8)+(4*0)+(3*9)+(2*7)+(1*2)=130
130 % 10 = 0
So 52809-72-0 is a valid CAS Registry Number.

[bmim]OH-promoted one-pot, three-component synthesis of β-nitro sulfides in water

Movassagh, Barahman

, p. 1114 - 1117 (2016/07/27)

A task-specific ionic liquid, [bmim]OH, has been found to be a highly efficient catalyst for one-pot, three-component coupling of aryl aldehydes, nitromethane, and thiols for the synthesis of β-nitro sulfides in water. The main advantages of the present p

Green procedure for the synthesis of β-nitro sulfides by Michael addition of thiols to nitroolefins

Hui, Xin-Ping,Yin, Chao,Ma, Jun,Xu, Peng-Fei

experimental part, p. 676 - 690 (2009/07/18)

Michael addition of thiols to nitroolefins was carried out in water at room temperature without any catalyst, and β-nitro sulfides were obtained in excellent yields. This is the first example of Michael addition of thiols to nitroolefins in water without

Synthesis of aza-Henry products and enamines in water by Michael addition of amines or thiols to activated unsaturated compounds

Ziyaei-Halimehjani, Azim,Saidi, Mohammad R.

, p. 1244 - 1248 (2008/09/17)

Nitroamines and nitrothiols were synthesized in high yields by the Michael addition of amines and thiols to nitroolefins without using any catalyst. Also, the reaction of amines with dimethylacetylene dicarboxylate (DMAD) in water afforded the corresponding enamines.
