76573-34-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 76573-34-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,7 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76573-34:
(7*7)+(6*6)+(5*5)+(4*7)+(3*3)+(2*3)+(1*4)=157
157 % 10 = 7
So 76573-34-7 is a valid CAS Registry Number.

Acyl chloride/DABCO-promoted acetal migration of 1,2:4,5-di-O-isopropylidene-d-fructopyranose

Meng, Xiang-Bao,Li, Yun-Feng,Li, Zhong-Jun

, p. 1101 - 1104 (2007)

An unprecedented acetal migration was observed when 1,2:4,5-di-O-isopropylidene-d-fructose was treated with various acyl chlorides and 1,4-diaza-bicyclo[2.2.2]octane (DABCO). 2,3:4,5-Di-O-isopropylidene-d-fructose derivatives were isolated as the only pro

Electronic probing of ketone catalysts for asymmetric epoxidation. Search for more robust catalysts

Tian, Hongqi,She, Xuegong,Shi, Yian

, p. 715 - 718 (2007/10/03)

Equation presented Ketones with a fused oxazolidinone were synthesized and investigated to determine the electronic effect of the substituents at α-positions of ketone catalysts on the Baeyer-Villiger oxidation and catalytic properties for asymmetric epoxidation. These new ketones give high yields and ee's with only 1 5 mol % catalyst. The current studies further show that the electronic effect is very important for the kitone-catalyzed epoxidation.
