874194-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874194-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,9 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 874194-31:
(8*8)+(7*7)+(6*4)+(5*1)+(4*9)+(3*4)+(2*3)+(1*1)=197
197 % 10 = 7
So 874194-31-7 is a valid CAS Registry Number.

Synthesis of excitatory amino acid analogues
Goundry, William R. F.,Lee, Victor,Baldwin, Jack E.
, p. 2407 - 2410 (2008/02/10)
A general route to excitatory amino acid analogues has been developed as exemplified by the synthesis of A-1 and A-2. The key reactions involved were a Negishi coupling of Jackson's organozinc reagent with vinyl bromide 8 and subsequent ring closure of 15
