Check Digit Verification of cas no
The CAS Registry Mumber 142502-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,0 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142502-88:
(8*1)+(7*4)+(6*2)+(5*5)+(4*0)+(3*2)+(2*8)+(1*8)=103
103 % 10 = 3
So 142502-88-3 is a valid CAS Registry Number.

Birch reduction of four furopyridines 1a-d effected the characteristic cleavage of the furan ring, giving ethnylpyridinols 2a-d, vinylpyridinols 3b,d, and ethylpyridinols 4a-d, and the reduction of the furan ring, giving dihydrofuropyridine 5c,d.

This paper describes reactions of 3-bromo- 1a-d, 2-phenylthio- 5a-d and 2-phenylthio-3-bromofuropyridines 6a-d with n-butyl-, t-butyl- and methyllithium and lithioacetonitrile.Lithiation of compounds 1a-d with n-butyl- or methyllithium gave the parent furopyridines 2a-d and o-ethynylpyridinols 3a-d.Reaction of compounds 5a-d with methyllithium afforded o-(phenylthioethynyl)pyridinols 7a-d, which were also yielded by reaction of compounds 6a-d with t-butyl- or methyllithium.The phenylthio group in compounds 7a-d were substituted with t-butyl group by the reaction with excess t-butyllithium.In contrast, 2-phenylthio group in compounds 5a-d and 6a-d was substituted with cyanomethyl group by reaction with lithioacetonitrile to give compounds 11a-d and 10b,c respectively.
