Calculate Digit Verification of CAS Registry Number 478932-11:
(8*4)+(7*7)+(6*8)+(5*9)+(4*3)+(3*2)+(2*1)+(1*1)=195
195 % 10 = 5
So 478932-11-5 is a valid CAS Registry Number.

Mild method for cleavage of dehydroalanine units: Highly efficient conversion of nocathiacin I to nocathiacin IV

Regueiro-Ren, Alicia,Ueda, Yasutsugu

, p. 8699 - 8702 (2007/10/03)

Thiazolyl peptide antibacterial nocathiacin I (1) was converted to nocathiacin IV (4) in high yield using iodomethane and hydriodic acid in THF at 45 °C. Several simplified dehydroalanine-containing systems undergo dehydroalanine cleavage under the same conditions, although in these cases iodomethane is not needed for efficient conversion. The mild reaction conditions are in contrast with other methods described in the literature.
