Check Digit Verification of cas no

The CAS Registry Mumber 13073-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,7 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13073-28:
(7*1)+(6*3)+(5*0)+(4*7)+(3*3)+(2*2)+(1*8)=74
74 % 10 = 4
So 13073-28-4 is a valid CAS Registry Number.

Chromatography-free entry to substituted salicylonitriles: Mitsunobu-triggered domino reactions of salicylaldoximes

Whiting, Ellis,Lanning, Maryanna E.,Scheenstra, Jacob A.,Fletcher, Steven

, p. 1229 - 1234 (2015/01/30)

A mild and efficient one-pot procedure is described to transform salicylaldoximes into salicylonitriles using Mitsunobu chemistry. The reactions proceed through the corresponding 1,2-benzisoxazoles that undergo the Kemp elimination in situ to generate the

Facile one-pot transformation of phenols into o-cyanophenols

Nakai, Yuhta,Moriyama, Katsuhiko,Togo, Hideo

, p. 6077 - 6083 (2015/03/30)

The treatment of phenols with paraformaldehyde in the presence of MgCl2 and Et3N in THF at 80 C, followed by reaction with molecular iodine and aq. ammonia at room temperature provided the corresponding o-cyanophenols in moderate to good yields. The present reaction is a one-pot transformation of phenols into o-cyanophenols using much less expensive reagents than are typically used; the reaction is free of both transition-metals and cyanide. The utility of this reaction was highlighted during our preparation of Febuxostat from p-bromophenol.
