Check Digit Verification of cas no

The CAS Registry Mumber 5413-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5413-32:
(6*5)+(5*4)+(4*1)+(3*3)+(2*3)+(1*2)=71
71 % 10 = 1
So 5413-32-1 is a valid CAS Registry Number.

The Complex Anionic Rearrangements of Deprotonated α-Oximino Carbonyl Derivatives in the Gas Phase

Adams, Gregory W.,Bowie, John H.,Hayes, Roger N.

, p. 1809 - 1818 (2007/10/02)

α-Oximino ketones R1COC(NOH)R2 deprotonate preferentially to form R1COC(NO-)R2 and this anion decomposes by a variety of complex rearrangement processes.The two major fragmentations involve the following overall processes (i) and (ii). (i) R1COC(NO-)R2 R1CO2- + R2CN, and (ii) R1COC(NO-)CH2R -O(R1)C=C=CH2 + RNO (R=H or alkyl).It is proposed that the reaction (i) involves a four-centre reaction of O- at the carbonyl carbon.No evidence of a Beckmann-type rearrangement is indicated for α-oximino ketones.The corresponding deprotonated α-oximino keto ne O-methyl ethers also fragment by complex rearrangement.For example, MeCOC(NOMe)Me deprotonates to form two ions which are interconvertible on collisional activation.The enolate ion is the principial deprotonated species, and it decomposes by the overall process -CH2COC(NOMe)Me --> -CH2CN + CH2CO + MeOH.The other anion decomposes by loss of methanol.This is best rationalised either by the Beckmann process MeCOC(NOMe)CH2- --> -> --> CH2=C=NCOCH2- + MeOH, or a related Neber rearrangement.This investigation was aided by deuterium labelling, and product ion studies.
