130633-31-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130633-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130633-31:
(8*1)+(7*3)+(6*0)+(5*6)+(4*3)+(3*3)+(2*3)+(1*1)=87
87 % 10 = 7
So 130633-31-7 is a valid CAS Registry Number.

Silicon-Directed Diene Synthesis

Brown, Paul A.,Bonnert, Roger V.,Jenkins, Paul R.,Lawrence, Nicholas J.,Selim, Mohammed R.

, p. 1893 - 1900 (2007/10/02)

A synthesis of 2-substituted-1,3-dienes is reported which uses silicon as a control element: eight aldehydes were converted into α-silyl ketones by treatment with trimethylsilylmethylmagnesium chloride and rapid Collins oxidation.Addition of vinylmagnesiu

Synthesis of a Deoxyristomycinic Acid Derivative using Organomanganese Chemistry

Pearson, Anthony J.,Lee, Seung-Han,Gouzoules, Fred

, p. 2251 - 2254 (2007/10/02)

Coupling of (3-chloro-2-methylanisole)tricarbonylmanganese tetrafluoroborate with the phenoxide derived from methyl N-Boc-3-hydroxyphenylglycinate gave the diaryl ether manganese complex (6).This complex underwent regiospecific, stereoselective reaction with Schollkopf's chiral glycine enolate equivalent to give a mixture of dienyl-Mn(CO)3 complexes that were converted in a two-step sequence into the protected deoxyristomycinic acid derivative (12).
