Check Digit Verification of cas no

The CAS Registry Mumber 136805-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,0 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136805-79:
(8*1)+(7*3)+(6*6)+(5*8)+(4*0)+(3*5)+(2*7)+(1*9)=143
143 % 10 = 3
So 136805-79-3 is a valid CAS Registry Number.

Synthesis and Reactions of 3-Hydroxy-2-nosyloxy Esters Produced by the Stereoselective Reduction of 2-Nosyloxy-3-keto Esters

Hoffman, Robert V.,Kim, Hwa-Ok

, p. 6759 - 6764 (2007/10/02)

The reduction of 2-nosyloxy-3-keto esters is an effective method for the preparation of 3-hydroxy-2-nosyloxy esters.The reduction is stereoselective for the syn isomer.The anti isomer can be produced as the major product by the addition of p-nitrobenzenesulfonyl peroxide to ketene bis-silyl acetal derivatives of 3-hydroxy esters.The diastereomers are separable chromatographically and can be converted stereospecifically to glycidic esters and 2-azido-3-hydroxy esters.As such they appear to have excellent potential as versatile synthetic intermediates for the synthesis of 1,2,3-trifunctional substances.
