Calculate Digit Verification of CAS Registry Number 58346-55:
(7*5)+(6*8)+(5*3)+(4*4)+(3*6)+(2*5)+(1*5)=147
147 % 10 = 7
So 58346-55-7 is a valid CAS Registry Number.

Studies on organometallic compounds. VII. Reaction of di-tert-butyl dicarbonate with α-trialkylstannyl derivatives of pyridine, quinoline, and isoquinoline

Yamamoto,Ouchi,Tanaka

, p. 916 - 919 (2007/10/02)

Di-tert-butyl dicarbonate was found to be effective for direct introduction of a tert-butoxycarbonyl group at the α-position of the pyridine nucleus via the trialkylstannyl group; reaction of α-trialkylstannyl derivatives of pyridine, quinoline, and isoquinoline with di-tert-butyl dicarbonate gave the corresponding α-tert-butoxycarbonyl derivatives in good yields, although small amounts of a variety of by-products were formed except in the case of pyridine.
