33608-30-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33608-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33608-30:
(7*3)+(6*3)+(5*6)+(4*0)+(3*8)+(2*3)+(1*0)=99
99 % 10 = 9
So 33608-30-9 is a valid CAS Registry Number.

GENERATION AND REACTIONS OF 2,3-DIHYDRO-2,3-bis-(METHYLENE)THIOPHENES

Chauhan, P. M. S.,Jenkins, G.,Walker, S. M.,Storr, R. C.

, p. 117 - 120 (2007/10/02)

2,3-Dihydro-2,3-bis-(methylene)thiophene and its benzo derivate, generated flash-pyrolytically, polymerise or are trapped with HCl and PhSH but only the latter gives Diels-Alder adducts; electrocyclisation of the 3-phenylmethylene derivate is accompained by skeletal rearrangement to give naphthothiophene.
