77342-57-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77342-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77342-57:
(7*7)+(6*7)+(5*3)+(4*4)+(3*2)+(2*5)+(1*7)=145
145 % 10 = 5
So 77342-57-5 is a valid CAS Registry Number.

Addition of Aldehydes to Activated Double Bonds, XXVIII. Preparations and Reactions of Alkoxy- and Acetoxy-2,5-diones

Stetter, Hermann,Mohrmann, Karl-Heinrich,Schlenker, Walter

, p. 581 - 596 (2007/10/02)

Thiazolium salt-catalyzed addition of aliphatic ether-aldehydes and pyrancarbaldehydes leads to corresponding 1-alkoxy-2,5-alkanediones 1-11 and pyranyl-1,4-alkanediones 28 - 47.In the same manner aldehydes react with 1-acetoxy-3-buten-2-one to give 1-acetoxy-2,5-alkanediones 12 - 19, which after saponification yield the 1-hydroxy-5-alkyl-2,5-pentanediones 20 - 27.
