Check Digit Verification of cas no

The CAS Registry Mumber 682770-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,7,7 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 682770-48:
(8*6)+(7*8)+(6*2)+(5*7)+(4*7)+(3*0)+(2*4)+(1*8)=195
195 % 10 = 5
So 682770-48-5 is a valid CAS Registry Number.

-

Paragraph 0029-0032; 0081-0087, (2021/05/29)

The invention discloses a novel synthesis method of a 3-carbonyl 5-hydroxyl ester compound with a structure as shown in a formula (1) defined in the description, which comprises the steps of taking a common carbon-based compound with a structure as shown in a formula (2) defined in the description and a polycarbonyl dicarboxylic acid unilateral ester compound (3) as raw materials, and directly and fully reacting in an organic solvent A under the condition of a transition metal catalyst, separating and purifying the reaction system after the reaction to obtain 3-carbonyl-5-hydroxy ester compound with high yield and high selectivity.

Candida Rugosa lipase-catalyzed kinetic resolution of β-hydroxy- β-arylpropionates and δ-hydroxy-δ-aryl-β-oxo-pentanoates

Xu, Chengfu,Yuan, Chengye

, p. 2169 - 2186 (2007/10/03)

A simple and convenient method was reported for the preparation of optically active β-hydroxy-β-arylpropionates, δ-hydroxy-δ- aryl-β-oxo-pentanoates and their butyryl derivatives via CRL-catalyzed hydrolysis. The optically active products are potential precursors of some chiral pharmaceuticals and natural products.

A Chemoenzymatic Approach to Optically Active 5-Hydroxy-3-oxocarboxylates

Xu, Chengfu,Zhang, Yonghui,Yuan, Chengye

, p. 485 - 488 (2007/10/03)

Enzymatic hydrolysis was applied to the preparation of certain chiral 5-hydroxy-3-oxo-carboxylates that are potential precursors for natural product synthesis via the formation of lactone derivatives and tetrahydropyran rings.
