41853-35-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41853-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,5 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41853-35:
(7*4)+(6*1)+(5*8)+(4*5)+(3*3)+(2*3)+(1*5)=114
114 % 10 = 4
So 41853-35-4 is a valid CAS Registry Number.

The Retro-Michael Reaction of 1,5-Dicarbonyl Compounds: Scope and Limitation

Wang, Jian-Xin,Li, Tong-Shuang

, p. 107 - 113 (2007/10/03)

Under catalysis of NaOH or KOH adsorbed on glass wool and by using steam distillation, (20R,S)-4,4,5,14-tetramethyl-18,19-dinor-13,17-seco-5β,8α,9β,10α,14β-cholestane-13,17-dione (1) and 3,14-dioxo-14,15-seco-5α-cholestan-15-al (4) gave good yield (>59 percent) of the corresponding tricyclic compounds (8a, 8b and 10a) via a retro-Michael reaction at 250 deg C. While 5-oxo-4-nor-3,5-secocholestan-3-oic acid (6) and ethyl 5-oxo-4-nor-3,5-secocholestan-3-oate (7) afforded low yield (15 percent) of the retro-Michael cleavage products (12a, 12b) at the same conditions. Thus, the retro-Michael reaction worked well for 1,5-diketones and 1,5-keto aldehydes but gave poor yield for 1,5-keto esters and 1,5-keto acids.
