Check Digit Verification of cas no

The CAS Registry Mumber 1078734-26-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,8,7,3 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1078734-26:
(9*1)+(8*0)+(7*7)+(6*8)+(5*7)+(4*3)+(3*4)+(2*2)+(1*6)=175
175 % 10 = 5
So 1078734-26-5 is a valid CAS Registry Number.

Efficient Thiophene Synthesis Mediated by 1,3-Bis(carboxymethyl)imidazolium Chloride: C-C and C-S Bond Formation

Gisbert, Patricia,Pastor, Isidro M.

, p. 4319 - 4325 (2020)

Thiophene derivatives have been prepared by means of a functionalized imidazolium salt [1,3-bis(carboxymethyl)imidazolium chloride] acting as a catalyst. The heterogeneous catalyst has allowed to carry out the reactions with no solvent or inert atmosphere

Sulfurative self-condensation of ketones and elemental sulfur: A three-component access to thiophenes catalyzed by aniline acid-base conjugate pairs

Nguyen, Thanh Binh,Retailleau, Pascal

, p. 387 - 390 (2018)

A sulfurative self-condensation method for constructing thiophenes 2 by a reaction between ketones 1 and elemental sulfur is reported. This reaction, which is catalyzed by anilines and their salts with strong acids, starts from readily available and inexp
