Check Digit Verification of cas no

The CAS Registry Mumber 1020991-05-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,9,9 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1020991-05:
(9*1)+(8*0)+(7*2)+(6*0)+(5*9)+(4*9)+(3*1)+(2*0)+(1*5)=112
112 % 10 = 2
So 1020991-05-2 is a valid CAS Registry Number.

, (2014)

A highly convenient method has been developed for the synthesis of (prop-2-ynyloxy) benzene and its derivatives. Differently substituted phenol and aniline derivatives were allowed to react with propargyl bromide in the presence of K2CO3/

Isopropanol and potassium tert-butoxide promoted intramolecular direct sp2 C-H functionalization: An expedient synthesis of 1,2,3-triazole annulated chromens and quinolones

Mondal, Biplab,Roy, Brindaban

supporting information, p. 6123 - 6127 (2015/10/28)

A series of 1,2,3-triazole annulated chromen and quinolone derivatives have been synthesized by means of direct sp2 C-H functionalization in the presence of iso-propanol and potassium tert-butoxide. The reaction proceeds through homolytic aroma

Hybrid system of metal/Bronsted acid relay catalysis for the intramolecular double hydroarylation and cationic cyclization of diyne diethers and diamines

Mo, Juntae,Eom, Dahan,Lee, Euichul,Lee, Phil Ho

supporting information; experimental part, p. 3684 - 3687 (2012/08/28)

We have developed a hybrid system of metal/Bronsted acid relay catalysis for the intramolecular double hydroarylation and cationic cyclization of diyne diethers and diamines to give 4,4′-bi(2H-chromene), bi(2H-quinoline), and dioxafluoranthenes starting f
