Check Digit Verification of cas no

The CAS Registry Mumber 90675-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,7 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90675-94:
(7*9)+(6*0)+(5*6)+(4*7)+(3*5)+(2*9)+(1*4)=158
158 % 10 = 8
So 90675-94-8 is a valid CAS Registry Number.

BROMINATION OF DIMETHYLACETALS WITH Br2-CHLOROTRIMETHYLSILANE-NaBr

Bellesia, Franco,Boni, Monica,Ghelfi, Franco,Pagnoni, Ugo Maria

, p. 629 - 632 (2007/10/02)

α-Bromodimethylacetals are obtained in excellent yields by treating dimethylacetals with Br2-NaBr-chlorotrimethylsilane in CH3OH/CH3CN (2:1). The method is suitable for large scale preparation.

THE MUKAIYAMA REACTION OF KETENE BIS(TRIMETHYLSILYL)ACETALS WITH α-HALO ACETALS - A CONVENIENT BUTENOLIDE SYNTHESIS

Demnitz, F. W. J.

, p. 6109 - 6112 (2007/10/02)

Ketene bis(trimethylsilyl) acetals were reacted with α-halo acetals giving β-alkoxy-γ-halo acids which were converted to butenolides by reaction with equivalents of base.This constitutes a novel and short butenolide synthesis.
