The CAS Registry Mumber 40808-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,0 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40808-52:
(7*4)+(6*0)+(5*8)+(4*0)+(3*8)+(2*5)+(1*2)=104
104 % 10 = 4
So 40808-52-4 is a valid CAS Registry Number.

A Facile Route to 4,5,6,7-Tetrahydrothiophenes and Benzothiophenes

Nishio, Takehiko,Okuda, Norikazu,Kashima, Choji

, p. 1437 - 1438 (2007/10/02)

2-Substituted tetrahydro- and cyclopentathiophenes 2 were produced in high yields by treatment of the semi-cyclic trisubstituted 1,4-diketones 1 such as 2-phenacylcyclohexan-1-one, 2-acetonylcyclohexan-1-one, and 2-phenacylcyclopentan-1-one, with Lawesson's reagent.
