Check Digit Verification of cas no

The CAS Registry Mumber 1259986-76-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,9,8 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1259986-76:
(9*1)+(8*2)+(7*5)+(6*9)+(5*9)+(4*8)+(3*6)+(2*7)+(1*6)=229
229 % 10 = 9
So 1259986-76-9 is a valid CAS Registry Number.

Synthesis of a tetrasaccharide related to the triterpenoid saponin isolated from Schima noronhae

Verma, Priya,Raj, Ritu,Roy, Bimalendu,Mukhopadhyay, Balaram

experimental part, p. 2413 - 2418 (2010/12/25)

A concise synthesis of a tetrasaccharide related to the cell-growth inhibitory triterpenoid saponin isolated from Schima noronhae is reported. A late stage 2,2,6,6-tetramethylpiperidinyloxy (TEMPO)-mediated oxidation of a primary hydroxyl group to carboxylic acid has been achieved under phase-transfer conditions. Stereoselective glycosylations were carried out using thioglycoside or glycosyl trichloroacetimidate activation using sulfuric acid immobilized on silica (H2SO4-silica) in conjunction with N-iodosuccinimide and alone, respectively.
