29280-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29280-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,2,8 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 29280-23:
(7*2)+(6*9)+(5*2)+(4*8)+(3*0)+(2*2)+(1*3)=117
117 % 10 = 7
So 29280-23-7 is a valid CAS Registry Number.

Chemoselective and chemospecific protection and deprotection of a carbonyl group using polystyrene divinylbenzene sulfonic acid

Verma, Sanjeev K.,Sathe, Manisha,Kaushik

experimental part, p. 1701 - 1707 (2010/07/15)

Chemospecific protection of one carbonyl group of two identical carbonyls of 2,2-dialkyl-1,3-cyclohexanedione and chemoselective protection of aliphatic or aromatic carbonyls in the presence of conjugated carbonyl compounds using cross-linked polystyrene divinyl benzene sulfonic acid (SPS) as a heterogeneous catalyst has been demonstrated.

A FACILE AND EFFICIENT METHOD FOR MONOKETALIZATION OF 1,4-CYCLOHEXANEDIONE

Babler, James H.,Spina, Kenneth P.

, p. 39 - 44 (2007/10/02)

Using a suitable hydrocarbon solvent such as hexane, continuous extraction of an aqueous solution of 1,4-cyclohexanedione containing 2,2-dimethyl-1,3-propanediol in molar excess and sulfuric acid as a catalyst afforded 1,4-cyclohexanedione mono-2,2-dimethyltrimethylene ketal (1b) in 85percent yield.
