Check Digit Verification of cas no
The CAS Registry Mumber 190714-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,1 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 190714-69:
(8*1)+(7*9)+(6*0)+(5*7)+(4*1)+(3*4)+(2*6)+(1*9)=143
143 % 10 = 3
So 190714-69-3 is a valid CAS Registry Number.

Control of enantioselectivity in the baker's yeast asymmetric reduction of γ-chloro β-diketones to γ-chloro (S)-β-hydroxy ketones
Cui, Jing-Nan,Ema, Tadashi,Sakai, Takashi,Utaka, Masanori
, p. 2681 - 2692 (1998)
1-Chloro-2,4-alkanediones 1a-f prepared in one step were reduced using baker's yeast to afford 1-chloro-2-hydroxy-4-alkanones 2a-f regioselectively in S 29% to R 58% ee. Use of a small amount of organic solvents to dissolve the substrate enhanced the enantiomeric excess in favor of the S configuration. The function of the organic solvents was studied with reducing enzymes isolated from baker's yeast. Some polar solvents selectively inhibited the enzymes, while nonpolar solvents enhanced the concentration of substrate in water. Application of inhibitors with heat-treatment and organic solvents as additives enhanced the enantiomeric excesses of the products to S 66-96% ee.
