38458-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38458-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38458-33:
(7*3)+(6*8)+(5*4)+(4*5)+(3*8)+(2*3)+(1*3)=142
142 % 10 = 2
So 38458-33-2 is a valid CAS Registry Number.

The Reaction of 2,3,4-Trichlorothiophene with Alkyllithium Reagents

Rahman, Mohammed T.

, p. 249 - 254 (1983)

2,3,4-Trichlorothiophene undergoes metal-hydrogen exchange with one equivalent of butyllithium in THF at -78 deg C to give trichloro-2-thienyllithium in 91percent yield.No metal-halogen exchange is observed to have taken place.With t-butyllithium under similar conditions, however, the metal-halogen exchange reaction occurs but only to the extent of 8percent; the main reaction remains to be the metal-hydrogen exchange. 2,3,4-Trichlorothiophene reacts with two equivalents of butyllithium in ether at -5 deg C to give 3,4-dichloro-2,5-dilithiothiophene in 96percent yield. - Keywords: 3,4-Dichloro-2,5-dilithiothiophene; Lithium-chlorine exchange; Trichloro-2-thienyllithium; 2,3,4-Trichlorothiophene
