89523-59-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89523-59-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89523-59:
(7*8)+(6*9)+(5*5)+(4*2)+(3*3)+(2*5)+(1*9)=171
171 % 10 = 1
So 89523-59-1 is a valid CAS Registry Number.

A highly selective sulfinate ester probe for thiol bioimaging

Malwal, Satish R.,Labade, Ajay,Andhalkar, Abhijeet S.,Sengupta, Kundan,Chakrapani, Harinath

, p. 11533 - 11535 (2014)

We describe here hitherto unexplored chemistry of the sulfinate ester functional group as being highly selective towards nucleophilic substitution by thiols at physiological pH. Using this cleavable trigger, an optical thiol probe that is suitable for thi

Model Reaction of Self-Condensation of Sulfenic Acids. Kinetic Investigation for the Reaction of Methyl Benzenesulfenate with trans-Decalin-9-sulfenic Acid and 2-Methyl-2-propanesulfenic Acid

Yoshimura, Toshiaki,Hamada, Kazuhiro,Yamazaki, Satoru,Shimasaki, Choichiro,Ono, Shin,Tsukurimishi, Eiichi

, p. 211 - 218 (2007/10/02)

Reaction of 2-methyl-2-propanesulfenic acid (1) with methyl arenesulfenates (2) gave S-aryl 2-methyl-2-propanethiosulfinates quantitatively, and kinetic investigation was carried out.Second-order rate dependence (first-order in methyl benzenesulfenate (2a
