Check Digit Verification of cas no
The CAS Registry Mumber 88744-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,7,4 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 88744-04:
(7*8)+(6*8)+(5*7)+(4*4)+(3*4)+(2*0)+(1*4)=171
171 % 10 = 1
So 88744-04-1 is a valid CAS Registry Number.

9-Fluorenylmethyl Pentafluorophenyl Carbonate as a Useful Reagent for the Preparation of N-9-Fluorenylmethyloxycarbonylamino Acids and their Pentafluorophenyl Esters
Schoen, Istvan,Kisfaludy, Lajos
, p. 303 - 305 (2007/10/02)
9-Fluorenylmethyl pentafluorophenyl carbonate is a useful reagent for the efficient, side reaction-free introduction of N-9-fluorenylmethyloxycarbonyl protecting group into amino acids and for the subsequent preparation of their pentafluorophenyl esters.Some new compounds of both types are described.
