157428-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 157428-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,2 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157428-51:
(8*1)+(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*5)+(1*1)=148
148 % 10 = 8
So 157428-51-8 is a valid CAS Registry Number.

Lithiation of 2-aryl-2-(chloroaryl)-1,3-dioxolanes and its application in the synthesis of new ortho-functionalized benzophenone derivatives

Lukacs, Gyula,Porcs-Makkay, Marta,Simig, Gyula

, p. 4130 - 4140 (2007/10/03)

2-Aryl-2-(chloroaryl)-1,3-dioxolanes 4 were lithiated ortho to the ketal group of the chloroaryl ring by treatment with butyllithium in THF between -78 and 0°C. The site selectivity of some of the deprotonation reactions was rationalized by the long-range effect of the 4-chloro substituent. The lithio species thus generated were treated with various electrophiles to give ortho-functionalized benzophenone derivatives. Intramolecular competition between the aryl rings was observed in the lithiation of 2-(4-chlorophenyl)-2- (4-fluorophenyl)-1,3-dioxolane (4s). Wiley-VCH Verlag GmbH & Co.
