Check Digit Verification of cas no

The CAS Registry Mumber 78370-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,7 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 78370-86:
(7*7)+(6*8)+(5*3)+(4*7)+(3*0)+(2*8)+(1*6)=162
162 % 10 = 2
So 78370-86-2 is a valid CAS Registry Number.

LITHIATION OF SOME 3THIOPHENES AND INTRAMOLECULAR TRANSMETALATION

Gronowitz, Salo,Stenhammar, Karin,Svensson, Leif

, p. 947 - 959 (2007/10/02)

The reaction of some halo-1-(thienyl)-2-phenylethanes such as 3-(2-phenylethyl)thiophene (1), 3-thiophene (2), 4--2-methylthiophene (3) and 4--2-chlorothiophene (4) with butyllithium and lithium diisopropylamide (LDA) under various conditions has been investigated.Competition between halogen-metal exchange in the benzene ring and metalation of thiophene ring was observed and an intramolecular transmetalation reaction was found.
