53561-17-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53561-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,6 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53561-17:
(7*5)+(6*3)+(5*5)+(4*6)+(3*1)+(2*1)+(1*7)=114
114 % 10 = 4
So 53561-17-4 is a valid CAS Registry Number.

Synthesis of ketone O-allyloximes and O-propargyloximes in KOH-DMSO system

Tarasova,Shmidt,Sinegovskaya,Petrova,Sobenina,Mikhaleva,Brandsma,Trofimov

, p. 1581 - 1586 (2007/10/03)

In reaction of ketone oximes with allyl bromide and propargyl chloride in KOH - DMSO system were obtained in good yield previously unknown ketone O-allyloximes and O-propargyloximes. The reactions are accompanied with minor regeneration of ketones (up to 12%, mainly 1-5%).

O-ALLYL ETHER AS A NEW PROTECTIVE GROUP FOR OXIMES AND ITS PALLADIUM-CATALYZED DEPROTECTION.

Yamada, Toshiro,Goto, Kuniaki,Mitsuda, Yasuhiro,Tsuji, Jiro

, p. 4557 - 4560 (2007/10/02)

Oximes are protected by O-allyl ether formation, and their palladium-catalyzed deallylation using triethylammonium formate as a reductant proceeds smoothly in boiling ethanol under mild conditions offering a good protective method for oximes.
