142231-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142231-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,2,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 142231-83:
(8*1)+(7*4)+(6*2)+(5*2)+(4*3)+(3*1)+(2*8)+(1*3)=92
92 % 10 = 2
So 142231-83-2 is a valid CAS Registry Number.

, p. 569 - 570 (2007/10/02)
The 3,4-dihydro-2H-1,2-benzothiazine 1,1-dioxides were prepared by reduction of the corresponding 1,2-benzothiazin-2-ones with diborane.The latter were obtained by the action of primary amines on 4,5-dimethoxy-2-carbomethoxymethylbenzenesulfonyl chloride
