Check Digit Verification of cas no

The CAS Registry Mumber 82238-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82238-72:
(7*8)+(6*2)+(5*2)+(4*3)+(3*8)+(2*7)+(1*2)=130
130 % 10 = 0
So 82238-72-0 is a valid CAS Registry Number.

Singlet Oxygenation and Triazolinedione Addition to Spirofluorene-1,3,5-cycloheptatriene

Adam, Waldemar,Duerr, Heinz,Pauly, Karl-Heinz,Peters, Eva-Maria,Peters, Karl,et al.

, p. 1333 - 1338 (2007/10/02)

Spirocyclopentadiene-, 1,4-diphenylspirocyclopentadiene-, and 1,2,3,4-tetrachlorospirocyclopentadiene-1,3,5-cycloheptatrienes (1a-c) all afford urazoles 3a-c with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) in which cycloaddition takes place at the cyclope

CYCLOADDITION OF SINGLET OXYGEN AND TRIAZOLINEDIONE (TAD) WITH SPIROCYCLOPENTADIENYL-1,3,5-CYCLOHEPTATRIENES: TROPILIDENE VERSUS NORCARADIENE REACTIVITY

Adam, Waldemar,Rebollo, Hector,Duerr, Heinz,Pauly, Karl-Heinz,Peters, Karl,et al.

, p. 923 - 926 (2007/10/02)

4-Methyl-1,2,4-triazoline-3,5-dione (MTAD) gives with 7-spirofluorenyl-1,3,5-cycloheptatriene (1d) initially the norcaradiene-type urazole (N3d) which at ambient temperatures rearranges into (6d), while 1O2 gives the tropilidene-type endoperoxide (T4d).
