87013-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87013-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87013-23:
(7*8)+(6*7)+(5*0)+(4*1)+(3*3)+(2*2)+(1*3)=118
118 % 10 = 8
So 87013-23-8 is a valid CAS Registry Number.

STEREOCONTROLLED EPOXY-EPIMINATION OF 1,3-CYCLOHEXADIENE
Vaerman, Jean-Luc,Viehe, Heinz G.
, p. 3183 - 3188 (2007/10/02)
1,3-cyclohexadiene yields with complete stereocontrol via oxazine (14) the new epoxy-epimine (15).The observed N-substituent effect, especially with the captodative vinyl group as oxazine isomerisation inducer, indicates a biradical mechanism.The use of t
