Check Digit Verification of cas no

The CAS Registry Mumber 140627-35-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,2 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 140627-35:
(8*1)+(7*4)+(6*0)+(5*6)+(4*2)+(3*7)+(2*3)+(1*5)=106
106 % 10 = 6
So 140627-35-6 is a valid CAS Registry Number.

Metal-free reduction of unsaturated carbonyls, quinones, and pyridinium salts with tetrahydroxydiboron/water

Li, Tiejun,Peng, Henian,Tang, Wenjun,Tian, Duanshuai,Xu, Guangqing,Yang, He

, p. 4327 - 4337 (2021/05/31)

A series of unsaturated carbonyls, quinones, and pyridinium salts have been effectively reduced to the corresponding saturated carbonyls, dihydroxybenzenes, and hydropyridines in moderate to high yields with tetrahydroxydiboron/water as a mild, convenient, and metal-free reduction system. Deuterium-labeling experiments have revealed this protocol to be an exclusive transfer hydrogenation process from water. This journal is

Oxidative coupling and hydroxylation of phenol over transition metal and acidic zeolites: Insights into catalyst function

Li, Jerry Pui Ho,Kennedy, Eric,Stockenhuber, Michael

, p. 9 - 15 (2014/03/21)

Reaction of phenol with hydrogen peroxide over H-MFI, Fe-MFI, H-BEA, Fe-BEA and TS-1 zeolite catalysts was investigated. Over H-BEA, biphenyl product was observed. It is suggested, that the larger pore size of H-BEA facilitates coupling of two phenol molecules. Two distinct reaction mechanisms are proposed for acid and redox catalysts.

A direct approach to 5-hydroxybenzofurans via a platinum-catalyzed domino rearrangement/5-endo-dig cyclization reaction of quinols

Kim, Ikyon,Kim, Kyungsun,Choi, Jungeun

scheme or table, p. 8492 - 8495 (2010/03/01)

(Chemical Equation Presented) A highly efficient and atom-economical construction of 2-substituted 5-hydroxybenzofurans was accomplished by employing a platinum-catalyzed domino dienone-phenol rearrangement/5-endo-dig cyclization reaction of quinols beari
