74761-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74761-84-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,6 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74761-84:
(7*7)+(6*4)+(5*7)+(4*6)+(3*1)+(2*8)+(1*4)=155
155 % 10 = 5
So 74761-84-5 is a valid CAS Registry Number.

A New Method for the α-Vinylation of Protected α-Amino Acids; Ethylene Oxide as Vinyl Cation Equivalent
Berkowitz, David B.
, p. 1819 - 1829 (2007/10/02)
A convenient and conceptually new strategy for the transformation of α-amino acids into the corresponding α-vinyl amino acids is described; commercially available ethylene oxide serves as a vinyl cation equivalent.
