111303-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111303-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,3,0 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 111303-32:
(8*1)+(7*1)+(6*1)+(5*3)+(4*0)+(3*3)+(2*3)+(1*2)=53
53 % 10 = 3
So 111303-32-3 is a valid CAS Registry Number.

SYNTHESIS AND CYCLOADDITION REACTION OF 2a,4,5-TRIAZABENZAZULENE DERIVATIVES
Abe, Noritaka,Gomi, Atsuko
, p. 767 - 772 (2007/10/02)
2a,4,5-Triazabenzazulene derivatives (2) were synthesized by the reaction of 8-hydrazino-3-phenyl-1-azaazulenes (1) with triethyl orthoformate. 2-Chloro substituted compound (2b) was easily hydrolized on silica gel and gave (2-chloro-8-imino-3-phenyl-
