863976-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 863976-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,9,7 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 863976-68:
(8*8)+(7*6)+(6*3)+(5*9)+(4*7)+(3*6)+(2*6)+(1*8)=235
235 % 10 = 5
So 863976-68-5 is a valid CAS Registry Number.

Extending pummerer reaction chemistry. Application to the oxidative cyclization of tryptophan derivatives
Feldman, Ken S.,Karatjas, Andrew G.
, p. 2849 - 2852 (2007/10/03)
(Equation Presented) The diastereoselective oxidative cyclization of a β-oxygenated tryptophan derivative is reported. This process, which utilizes a new variant of the Pummerer reaction, may have application in TMC-95A synthesis.
