62702-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 62702-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,7,0 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 62702-04:
(7*6)+(6*2)+(5*7)+(4*0)+(3*2)+(2*0)+(1*4)=99
99 % 10 = 9
So 62702-04-9 is a valid CAS Registry Number.

, p. 236 - 237 (2007/10/02)
Thermolysis of several new 2-(ω-alkenyl)-3-sulpholenes, prepared by direct deprotonation and alkylation of 3-sulpholenes, led to cheletropic extrusion of SO2 followed by intramolecular Diels-Alder reaction to yield the corresponding hydroindans and hydronaphthalenes.
