88877-45-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88877-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,8,7 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88877-45:
(7*8)+(6*8)+(5*8)+(4*7)+(3*7)+(2*4)+(1*5)=206
206 % 10 = 6
So 88877-45-6 is a valid CAS Registry Number.

A New Strategy for the High-Pressure Synthesis of Chiral Cryptands

Ostaszewski, Ryszard,Jacobsson, Ulla,Jurczak, Janusz

, p. 347 - 352 (2007/10/02)

A new strategy for the high-pressure synthesis of chiral cryptands is reported.Four chiral cryptands derived fro D-glucose, D-galactose, D-mannose and L-tartaric acid are prepared in a short reaction sequence.

High-pressure Approach to the Synthesis of Novel Chiral Cryptands Derived from Methyl 4,6-O-Benzylidene-α-D-manno-, -α-D-galacto-, and -α-D-gluco-pyranoside

Pietraszkiewicz, Marek,Salanski, Piotr,Jurczak, Janusz

, p. 1184 (2007/10/02)

Diaza crown ethers derived from sugars react under high pressure with bis-(2-iodoethyl) ether to give the quaternary salts in quantitative yield and their subsequent demethylation with triphenylphosphine affords chiral cryptands in high yield.
