Check Digit Verification of cas no

The CAS Registry Mumber 123795-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,9 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123795-50:
(8*1)+(7*2)+(6*3)+(5*7)+(4*9)+(3*5)+(2*5)+(1*0)=136
136 % 10 = 6
So 123795-50-6 is a valid CAS Registry Number.

A MODIFIED BENZHYDRYLAMINE - A USEFUL HANDLE REAGENT FOR Fmoc BASED SOLID PHASE SYNTHESIS OF PEPTIDE AMIDES

Funakoshi, Susumu,Murayama, Eigoro,Guo, Lili,Fujii, Nobutaka,Yajima, Haruaki

, p. 2791 - 2800 (2007/10/02)

Usefulness of a dimethoxybenzhydrylamine derivative, 3-(3-(Fmoc-amino-4-methoxyphenylmethyl)-4-methoxyphenyl)propionic acid, for Fmoc-based solid phase synthesis of peptide amides was demonstrated by preparation of three biologically active peptide amides, i.e. tetragastrin, neuromedin B and vasopressin. 1M trimethylsilyl bromide-thioanisole (molar ration 1 : 1) in trifluoroacetic acid was recommended as a deprotecting reagent for releasing the peptide amides from the resin.
