52557-25-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52557-25-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,5,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52557-25:
(7*5)+(6*2)+(5*5)+(4*5)+(3*7)+(2*2)+(1*5)=122
122 % 10 = 2
So 52557-25-2 is a valid CAS Registry Number.

Type III Intramolecular Cycloadditions of Vinylketenes

Snider, Barry B.,Allentoff, Alban J.,Kulkarni, Yashwant S.

, p. 5320 - 5328 (2007/10/02)

Treatment of trans α,β-unsaturated acid chlorides with Et3N in benzene at reflux gives a ca. 1:1 mixture of cis and trans α,β-unsaturated ketenes in excellent yield.If there is a second double bond in the side chain, the cis isomer undergoes a type III intramolecular cycloaddition to produce a bicyclohept-3-en-6-one and/or a bicyclohept-2-en-6-one in 30-50percent yield from the acid chloride.The effect of substituents on the stereochemistry and regiochemistry of the cycloaddition is described.
