77300-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77300-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,0 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77300-64:
(7*7)+(6*7)+(5*3)+(4*0)+(3*0)+(2*6)+(1*4)=122
122 % 10 = 2
So 77300-64-2 is a valid CAS Registry Number.

THE CONVERSION OF L-GLUTAMATE TO L-TYROSINE
Danishefsky, Samuel,Morris, Joel,Clizbe, Lane A.
, p. 1205 - 1208 (2007/10/02)
The Diels Alder reaction of a glutamate derived dienophile with trans-1-methoxy-3-trimethylsilyloxy-1,3-butadiene affords a spirodienone.This, upon treatment with aqueous base leads to N-CBz-tyrosine.Optical activity is substantially maintained throughout the process.
