1257555-16-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1257555-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,5,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1257555-16:
(9*1)+(8*2)+(7*5)+(6*7)+(5*5)+(4*5)+(3*5)+(2*1)+(1*6)=170
170 % 10 = 0
So 1257555-16-0 is a valid CAS Registry Number.

Stereoselective synthesis of enynones via base-catalyzed isomerization of 1,5-disubstituted-2,4-pentadiynyl silyl ethers or their alcohol derivatives

Chen, Jingjin,Fan, Guoqin,Liu, Yuanhong

supporting information; experimental part, p. 4806 - 4810 (2010/12/19)

1,5-Disubstituted-2,4-pentadiynyl silyl ethers undergo smooth desilylative isomerization to afford cis-enynones as major products with moderate stereoselectivities in the presence of a catalytic amount of KOtBu or DBU. While the isomerization reactions of their alcohol derivatives catalyzed by KOH, KOtBu or NaH take place efficiently to produce trans-enynones with high stereoselectivities. These reactions provide convenient and practical routes for the synthesis of enynones with a wide range of substitution groups.
