1242770-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1242770-93-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,7,7 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1242770-93:
(9*1)+(8*2)+(7*4)+(6*2)+(5*7)+(4*7)+(3*0)+(2*9)+(1*3)=149
149 % 10 = 9
So 1242770-93-9 is a valid CAS Registry Number.

Facile access to boryltetralins and borylnaphthalenes via a cycloaddition using o-quinodimethanes
Yoshida, Hiroto,Mukae, Masashi,Ohshita, Joji
, p. 5253 - 5255 (2010/08/22)
Borylalkenes are found to serve as efficient dienophiles in a cycloaddition reaction with o-quinodimethanes, giving diverse boryltetralins, which are convertible into borylnaphthalenes via an oxidative aromatization.
