Check Digit Verification of cas no

The CAS Registry Mumber 81788-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,8 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81788-26:
(7*8)+(6*1)+(5*7)+(4*8)+(3*8)+(2*2)+(1*6)=163
163 % 10 = 3
So 81788-26-3 is a valid CAS Registry Number.

MICHAEL-ADDITION REACTIONS OF LEVOGLUCOSENONE

Shafizadeh, Fred,Ward, David D.,Pang, David

, p. 217 - 230 (2007/10/02)

The Michael-addition reactions of levoglucosenone with diethyl malonate, ethyl cyanoacetate, 2-nitropropane, and 2-methylcyclohexanone have been examined, using a variety of catalysts.This reaction may be conveniently used to prepare, in reasonable yields, 4-substituted levoglucosenone derivatives having the D-erythro configuration.Better yields of the diethyl malonate adduct were obtained on using bis(2,4-pentanedionate)-Ni(II) as the catalyst.
