Check Digit Verification of cas no

The CAS Registry Mumber 264260-38-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,2,6 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 264260-38:
(8*2)+(7*6)+(6*4)+(5*2)+(4*6)+(3*0)+(2*3)+(1*8)=130
130 % 10 = 0
So 264260-38-0 is a valid CAS Registry Number.

AMACE1: Versatile aminoacetamide electrophore reagent

Lu, Rong J.,Giese, Roger W.

, p. 1798 - 1801 (2007/10/03)

Acetamide, 2-amino-N-[[3,5-bis(trifluoromethyl)phenyl]methyl]-N-methyl-, monohydrochloride, which we have named AMACE1, was synthesized in three steps starting from N-tritylglycine. AMACE1 was coupled via its primary amine group (pK(a) 8.2) under aqueous conditions to four model analytes for oxidative sugar damage to DNA: glycolate, 3-hydroxy-2-butanone, 3-phenylbutyraldehyde, and α-hydroxy-γ-butyrolactone, relying on cyanoborohydride for coupling to a keto function and a water-soluble carbodiimide for coupling to a carboxyl function. Further reaction with butyric anhydride led to products that could be detected by gas chromatography/electron capture mass spectrometry when 1 μL of ethyl acetate containing essentially 20 amol of each product was injected, on the basis of selected ion monitoring of the analyte characteristic anion fragment from dissociative loss of the 3,5- bis(trifluoromethyl)phenylmethyl moiety: m/z 215, 289, 299, and 329, respectively. Since many small, organic analytes contain a keto or carboxylic acid group, AMACE1 should be useful in general in the area of trace organic analysis.
