Check Digit Verification of cas no
The CAS Registry Mumber 49675-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,7 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 49675-78:
(7*4)+(6*9)+(5*6)+(4*7)+(3*5)+(2*7)+(1*8)=177
177 % 10 = 7
So 49675-78-7 is a valid CAS Registry Number.

Acylating and arylsulfonylating ability of O-derivatives of isatin 3-oximes
Stankevicius,Terentiev,Janushene,Savickas
, p. 98 - 104 (2007/10/03)
O-Acyl and O-arylsulfonyl derivatives of isatin 3-oximes have been synthesized and their interaction with alcohols and amines has been investigated. It was established that none of the esters of 1-substituted isatin 3-oximes reacted with the indicated nucleophiles. 1-Unsubstituted O-aryl and O-arylsulfonyl derivatives react with amines as acylating agents even at room temperature, but O-acetyl derivatives only on heating. Acylamides or arylsulfamides respectively are formed in this way. O-Acyl derivatives do not react with alcohols at room temperature. Only O-benzoyl derivatives form ethyl benzoate on heating in ethanol. A comparative analysis of mass spectrometric data on the processes of acylation and arylsulfonylation is given.
