57740-07-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57740-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57740-07:
(7*5)+(6*7)+(5*7)+(4*4)+(3*0)+(2*0)+(1*7)=135
135 % 10 = 5
So 57740-07-5 is a valid CAS Registry Number.

The study of intramolecular tandem radical cyclizations of acylsilanes with radicalphiles attached on silicon

Tang, Kuo-Hsiang,Liao, Fang-Yu,Tsai, Yeun-Min

, p. 2037 - 2045 (2005)

Radical cyclizations of acylsilanes with radicalphilic pendant introduced on silicon proceeded in a tandem fashion to give spiro products containing a cyclic silyl ether skeleton. Because the alkoxysilyl group can be replaced with a hydroxy group through

Grignard reagents: Alkoxide-directed iodine-magnesium exchange at sp 3 centers

Fleming, Fraser F.,Gudipati, Subrahmanyam,Vu, Viet Anh,Mycka, Robert J.,Knochel, Paul

, p. 4507 - 4509 (2008/03/11)

(Chemical Equation Presented) Sequential addition of i-PrMgCl and BuLi to sp3 hybridized iodoalcohols triggers a facile iodine-metal exchange. Intercepting the resulting cyclic Grignard reagents with a slight excess of an electrophile leads to a diverse range of substituted alcohols. The iodine-magnesium exchange strategy is effective with 3-carbon iodoalcohols bearing alkyl substitutents on the carbinol or adjacent carbons and with the chain-extended homolog 4-iodobutan-1-ol.

Group transfer from silicon to carbon via tandem radical cyclizations of acylsilanes

Tsai, Yeun-Min,Tang, Kuo-Hsiang,Jiaang, Weir-Torn

, p. 7767 - 7770 (2007/10/03)

Tandem radical cyclizations of acylsilanes with alkene or alkyne functionalities attached to silicon afforded cyclic silyl ethers which were oxidatively hydrolyzed to give diols or ketone alcohols.
