4076-57-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4076-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4076-57:
(6*4)+(5*0)+(4*7)+(3*6)+(2*5)+(1*7)=87
87 % 10 = 7
So 4076-57-7 is a valid CAS Registry Number.

E-Stilbene derivatives synthesized by stereoselective reductive coupling of benzylic gem-dibromide promoted by Cu/polyamine

Cao, Hua,Wang, Qi

, p. 2703 - 2706 (2017/06/23)

Stereoselective reductive coupling reaction of benzylic gem-dibromide promoted by Cu/polyamine produces E-stilbene derivatives with high yield under mild conditions. It provides a short pathway to synthesize symmetrical and asymmetrical E-stilbene derivatives using cheap reagents and alkenyl-free starting material together with easy workup.

Improved Halogenation of Methyl Aromatics and Methyl Heteroaromatics: Unexpected Reactivity of Tetrahalogeno-diphenylglycolurils

Moretti, Florian,Poisson, Guillaume,Marsura, Alain

, p. 173 - 183 (2016/05/19)

1,3,4,6-Tetrachloro (TCDGU) and 1,3,4,6-tetrabromo-3α,6α-diphenylglycolurils smooth halogen oxidizers have been exploited in a new direction as reagents for free radical substitution toward some N-halosuccinimide nonreactive bis-heterocycles. An unexpected selectivity and reactivity were observed with methyl benzenes, methyl heterocycles, and methyl-bis-heterocycles of interest. A chemometric study has been performed to optimize five independent factors of the chlorination reaction with TCDGU. The predictive model was established either for the halogenation conversion and the ratio of monochlorination.

Thiol-activated gem-dithiols: A new class of controllable hydrogen sulfide donors

Zhao, Yu,Kang, Jianming,Park, Chung-Min,Bagdon, Powell E.,Peng, Bo,Xian, Ming

supporting information, p. 4536 - 4539 (2015/01/08)

A class of novel thiol-activated H2S donors has been developed on the basis of the gem-dithiol template. These donors release H2S in the presence of cysteine or GSH in aqueous solutions as well as in cellular environments.
