Check Digit Verification of cas no

The CAS Registry Mumber 1263386-73-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,3,8 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263386-73:
(9*1)+(8*2)+(7*6)+(6*3)+(5*3)+(4*8)+(3*6)+(2*7)+(1*3)=167
167 % 10 = 7
So 1263386-73-7 is a valid CAS Registry Number.

Synthesis of new carbohydrate-derived ketones as organocatalysts in the enantioselective epoxidation of arylalkenes. Part 2: Chiral ketones from sugars

Vega-Pérez, José M.,Vega-Holm, Margarita,Peri?án, Ignacio,Palo-Nieto, Carlos,Iglesias-Guerra, Fernando

experimental part, p. 364 - 372 (2011/03/20)

A range of new, somewhat complex, stereochemically varied, and structurally related carbohydrate-derived ketones were synthesised by a simple method from the carbohydrate precursor (d-gluco and d-galacto derivatives). The common skeleton possesses the keto function sited on a seven-membered ring fused to positions 2 and 3 of the sugar moiety. Their chirality transfer capability in the dioxirane-mediated epoxidation of arylalkenes was evaluated. Copyright
