Calculate Digit Verification of CAS Registry Number 557086-54:
(8*5)+(7*5)+(6*7)+(5*0)+(4*8)+(3*6)+(2*5)+(1*4)=181
181 % 10 = 1

The first method for protection-deprotection of the indole 2,3-π bond

Baran, Phil S.,Guerrero, Carlos A.,Corey

, p. 1999 - 2001 (2003)

(Matrix presented) The scope and generality of a new reaction of indoles with MTAD is discussed. In most cases the ene-type reaction proceeds within seconds or minutes at 0°C to provide the urazole adducts in high yield. This reaction provides the first method for protecting the indole 2,3-double bond since the urazole adducts can be reconverted to the starting indole (retro-ene) simply by heating.
