90426-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90426-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90426-18:
(7*9)+(6*0)+(5*4)+(4*2)+(3*6)+(2*1)+(1*8)=119
119 % 10 = 9
So 90426-18-9 is a valid CAS Registry Number.

ON THE INTERMEDIACY OF BICYCLOHEPT-6-YNE, A CYCLOBUTYNE DERIVATIVE
Baumgart, Klaus-Dieter,Szeimies, Guenter
, p. 737 - 740 (2007/10/02)
Treatment of 6-chloro-, 6-bromo-, and 6-iodobicyclohept-6-ene, respectively, with LDA in the presence of LiSPh led to identical mixtures of thioethers 3e and 4a.The results are rationalized by the assumption that cyclobutyne 2 and carbene 7 are for
