797751-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 797751-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,9,7,7,5 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 797751-68:
(8*7)+(7*9)+(6*7)+(5*7)+(4*5)+(3*1)+(2*6)+(1*8)=239
239 % 10 = 9
So 797751-68-9 is a valid CAS Registry Number.

Pentafluorophenyl esters for temporary carboxyl group protection in solid phase synthesis of N-linked glycopeptides
Meldal, Morten,Book, Klaus
, p. 6987 - 6990 (1990)
The compound Ac3GlcNAcβ1-NH-Fmoc (3) was synthesized and transformed into the β-glucosyl amine (1) which was subsequently acylated with Fmoc-Asp(Cl)-O-Pfp (5) prepared from the readily available Fmoc-Asp(O-tBu)-O-Pfp (4). The resulting Fmoc-Asn
