Check Digit Verification of cas no

The CAS Registry Mumber 685141-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,1,4 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 685141-12:
(8*6)+(7*8)+(6*5)+(5*1)+(4*4)+(3*1)+(2*1)+(1*2)=162
162 % 10 = 2
So 685141-12-2 is a valid CAS Registry Number.

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

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

, p. 1295 - 1304 (1989)

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.
