7326-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7326-64-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,2 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7326-64:
(6*7)+(5*3)+(4*2)+(3*6)+(2*6)+(1*4)=99
99 % 10 = 9
So 7326-64-9 is a valid CAS Registry Number.

Aza-Diels-Alder reactions of 2-(phenylthio)-1,3-butadiene with simple iminium salts
Chou,Hung
, p. 1097 - 1104 (2001)
The titled compound 2 was readily prepared by thermal desulfonylation of 3-(phenylthio)-3-sulfolene (1). The aza-Diels-Alder reactions of 2 with some simple iminium salts gave the cyclized products 3-7 in good yield with complete control of regiochemistry
