Check Digit Verification of cas no

The CAS Registry Mumber 118629-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,2 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118629-71:
(8*1)+(7*1)+(6*8)+(5*6)+(4*2)+(3*9)+(2*7)+(1*1)=143
143 % 10 = 3
So 118629-71-3 is a valid CAS Registry Number.

Chemoselective reduction of 2,3-epoxy tosylates with DIBAL-H as a general route to enantiomerically-enriched 1-tosyloxy-2-alkanols

Michael Chong

, p. 7197 - 7200 (1994)

2,3-Epoxy tosylates may be reduced with DIBAL-H in CH2Cl2 or ether at -40°C to 1-tosyloxy-2-alkanols in high (94-98%) yields.

Arenesulfonate Derivatives of Homochiral Glycidol: Versatile Chiral Building Blocks for Organic Synthesis

Klunder, Janice M.,Onami, Tetsuo,Sharpless, K. Barry

, p. 1295 - 1304 (2007/10/02)

The preparation of a series of crystalline arenesulfonate derivatives of enantiomerically enriched glycidol is described.The enhancement of optical purity by recrystallization was particularly successful for two of these derivatives, glycidyl tosylate and glycidyl 3-nitrobenzenesulfonate, which were obtained in 97 percent ee and 99 percent ee, respectively.Very high regioselectivity was observed in the reactions of these compounds with a variety of nucleophiles, including aryl oxides, Et2AlCN, organometallic reagents, and BH3-NaBH4.The application of this methodology to the synthesis of homochiral β-adrenergic blocking agents and homochiral terminal epoxides is discussed.
