Check Digit Verification of cas no

The CAS Registry Mumber 261713-62-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,1 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 261713-62:
(8*2)+(7*6)+(6*1)+(5*7)+(4*1)+(3*3)+(2*6)+(1*2)=126
126 % 10 = 6
So 261713-62-6 is a valid CAS Registry Number.

Facile ring transformation from gluconolactone to cyclitol derivative via spiro sugar ortho ester

Ohtake, Hiro,Ikegami, Shiro

, p. 457 - 459 (2007/10/03)

(Formula presented) A short step preparation of cyclitol derivative 8 which is a versatile synthon for the synthesis of valiolamine and its related compounds is described. Key steps in this preparation are a novel enol ether formation from spiro sugar ortho esters with AIMe3 and an intramolecular Aldol condensation of alkyl enol ethers catalyzed by ZnCl2 in THF-H2O. With these reactions, gluconolactone derivative 1 was efficiently converted into 8 in short steps.
