694490-96-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 694490-96-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,4,4,9 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 694490-96:
(8*6)+(7*9)+(6*4)+(5*4)+(4*9)+(3*0)+(2*9)+(1*6)=215
215 % 10 = 5
So 694490-96-5 is a valid CAS Registry Number.

Correlation of hydrolysis and desilylation of 2-[(trimethylsilyl)methyl] acrylate derivatives in aqueous alkali solutions

Kuroda, Chiaki,Sunakawa, Takeshi,Muguruma, Yuichi

scheme or table, p. 888 - 896 (2009/03/11)

Hydrolysis and desilylation reaction of 2-[(trimethylsilyl)methyl]acrylate (=2-[(trimethylsilyl)methyl] prop-2-enoate) derivatives were studied to evaluate the effect of the presence/absence of a further conjugating substituent (Schemes 3 and 4 and Tables 1 and 2). The substrates having a nonconjugating substituent at the acrylate moiety were stable to dilute alkali conditions, and afforded simple hydrolysis products under concentrated alkali conditions. In contrast, both hydrolysis and desilylation occurred from the substrates bearing conjugated substituents at the acrylate skeleton. The difference in reactivity can be explained in terms of the stabilization of the intermediate anion.
