Check Digit Verification of cas no

The CAS Registry Mumber 438245-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,2,4 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 438245-27:
(8*4)+(7*3)+(6*8)+(5*2)+(4*4)+(3*5)+(2*2)+(1*7)=153
153 % 10 = 3
So 438245-27-3 is a valid CAS Registry Number.

Synthesis of 3-(4-oxo-4H-3,1-benzoxazin-2-yl)-1-benzenesulfonyl chloride and its reactivity toward amines

Tarasov,Strikanova,Moskvichev,Timoshenko

, p. 87 - 89 (2002)

3-(4-Oxo-4H-3,1-benzoxazin-2-yl)-1-benzenesulfonyl chloride was synthesized, and reactivity of its functional groups was studied. Reactions of the title compound with equimolar amounts of aniline and piperidine gave the corresponding sulfonamides with retention of the benzoxazine moiety. The same reactions with excess amine resulted in opening of the oxazine ring and formation of o-(m-aminosulfonylbenzoylamino)benzamides.
