Check Digit Verification of cas no

The CAS Registry Mumber 181185-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,1,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181185-39:
(8*1)+(7*8)+(6*1)+(5*1)+(4*8)+(3*5)+(2*3)+(1*9)=137
137 % 10 = 7
So 181185-39-7 is a valid CAS Registry Number.

Method for synthesizing beta-hydroxy carbonyl compound by catalyzing asymmetric Aldol reaction in water phase

-

Paragraph 0046-0047, (2021/01/28)

The invention discloses a method for synthesizing a beta-hydroxy carbonyl compound by catalyzing asymmetric Aldol reaction in a water phase. The method comprises the following steps: in the water phase, catalyzing ketone and aldehyde with equal molar weig

Contrasting steric effects of the ketones and aldehydes in the reactions of the diisopinocampheyl enolborinates of methyl ketones with aldehydes

Ramachandran, P. Veeraraghavan,Wei-Chu, Xu,Brown, Herbert C.

, p. 4911 - 4914 (2007/10/03)

Treatment of the diisopinocampheylborinates of a representative series of methyl ketones with a representative series of aldehydes, both of differing steric requirements provides aldols whose enantiomeric purifies depend on the steric requirements of both the ketones and the aldehydes. This study has shown that increasing the steric requirements of the R group in the ketones has a pernicious effect on the ee, while increasing the steric requirements of the R group in the aldehydes exerts a beneficial effect on the ee.

C-C ASYMMETRIC BOND FORMATION MEDIATED BY OPTICALLY ACTIVE SULFOXIDES

Cinquini, Mauro

, p. 39 - 72 (2007/10/02)

Highly stereoselective C-C bond forming reactions can be performed with a variety of optically active sulfinyl derivatives to afford, after desulfurization, optically active sulfur-free products.
