1062309-62-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1062309-62-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,2,3,0 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1062309-62:
(9*1)+(8*0)+(7*6)+(6*2)+(5*3)+(4*0)+(3*9)+(2*6)+(1*2)=119
119 % 10 = 9
So 1062309-62-9 is a valid CAS Registry Number.

Stereoselective cyclopropanation of unsaturated acetals, using carbohydrates with d-gluco, l-rhamno and d-xylo configurations as chiral auxiliaries

Vega-Perez, Jose M.,Perinan, Ignacio,Vega, Margarita,Iglesias-Guerra, Fernando

, p. 1720 - 1729 (2008)

The stereoselective synthesis of (2-phenylcyclopropyl)methylidene acetals of sugar derivatives from methyl d-glucopyranoside, dodecyl N-acetyl-2-amino-2-deoxy-d-glucopyranoside, 1,2-O-isopropylidene-d-glucofuranose, methyl l-rhamnopyranoside and 1,2-O-isopropylidene-d-xylofuranose, as a chiral auxiliary, is described. The cyclopropanation reaction of the corresponding alkenylidene derivatives with CH2I2/ZnEt2 took place with different stereoselectivity, depending on the configuration on the acetal carbon, the size of the acetal ring, the sugar configuration, the protecting group of the hydroxyl groups of the sugar and the substitution of the unsaturated system. The stereochemistry of the new stereogenic centres was then determined by acid hydrolysis of the cyclopropane moiety of the chiral auxiliary, which was also recovered.
