171617-11-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 171617-11-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,6,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 171617-11:
(8*1)+(7*7)+(6*1)+(5*6)+(4*1)+(3*7)+(2*1)+(1*1)=121
121 % 10 = 1
So 171617-11-1 is a valid CAS Registry Number.

Trialkylsilyl triflimides as easily tunable organocatalysts for allylation and benzylation of silyl carbon nucleophiles with non-genotoxic reagents

Mendoza, Oscar,Rossey, Guy,Ghosez, Léon

supporting information; experimental part, p. 2571 - 2575 (2010/06/21)

Trialkylsilyl triflimides generated in situ are unique catalysts for the electrophilic benzylation or allylation of trialkylsilylenol ethers or allyl trialkylsilanes with non-genotoxic alkylating reagents such as benzyl and allyl acetates. In most cases the reactions are fast at room temperature and yields are high. The reaction works particularly well with electron-rich benzyl donors including derivatives of pyrrole, indole and furane.

Baker's yeast reduction of arylidenecycloalkanones

Fogliato, Giovanni,Fronza, Giovanni,Fuganti, Claudio,Lanati, Simonetta,Rallo, Roberta,Rigoni, Romina,Servi, Stefano

, p. 10231 - 10240 (2007/10/02)

The baker's yeast reduction of arylidene cycloalkanones 5, 6 and 7 occurs initially through the catalysis of different enzymes to give the saturation of the double bond leading to the saturated ketones 9, 15 and 22 and the carbonyl reduction to the (S) allylic alcohols 8a, 14 and 23, possessing 0.99, 0.85 and 0.66 ee, respectively. The latter act as inhibitors for the carbonyl reducing enzyme thus preventing the further reduction of the saturated ketone. These compounds in the absence of allylic alcohols are further reduced to a mixture of diastereomic saturated (S) alcohols of high-moderate enantiomeric purity. Reduction experiments in D2O indicate that saturation of the double bond of 5 occurs by β re face addition of hydrogen, as shown by the obtainment of 10'.
