Check Digit Verification of cas no

The CAS Registry Mumber 69200-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,0 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69200-90:
(7*6)+(6*9)+(5*2)+(4*0)+(3*0)+(2*9)+(1*0)=124
124 % 10 = 4
So 69200-90-4 is a valid CAS Registry Number.

Cycloaddition Reactions of Sulphines and Thiones with Azoalkenes

Bonini, Bianca F.,Maccagnani, Gaetano,Mazzanti, Germana,Rosini, Goffredo,Foresti, Elisabetta

, p. 2322 - 2327 (1981)

Fluorenethione S-oxide undergoes (2+4) cycloadditions with azoalkenes to yield 2H-1,2,3-thiadiazine 1-oxides together with a small amount of the regioisomeric 6H-1,3,4-thiadiazine 1-oxides.Fluorenethione, with azoalkenes, undergoes (2+4) regiospecific cycloaddition reactions leading to the formation of 6H-1,3,4-thiadiazine derivatives.Diarylsulphines and diarylthiones fail to react with azoalkenes.
