Check Digit Verification of cas no

The CAS Registry Mumber 84000-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,0,0 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84000-00:
(7*8)+(6*4)+(5*0)+(4*0)+(3*0)+(2*0)+(1*0)=80
80 % 10 = 0
So 84000-00-0 is a valid CAS Registry Number.

Synthesis of 9-Fluorenylmethyloxycarbonyl-Protected N-Alkyl Amino Acids by Reduction of Oxazolidinones

Freidinger, Roger M.,Hinkle, Jeffery S.,Perlow, Debra S.,Arison, Byron H.

, p. 77 - 81 (1983)

A new two-step synthesis of Fmoc-protected N-alkyl amino acids has been developed.The first step involves acid-catalyzed condensation of an Fmoc-protected amino acid with an aldehyde to form an oxazolidinone.This intermediate is then reduced with triethyl
