Check Digit Verification of cas no

The CAS Registry Mumber 59846-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,8,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 59846-87:
(7*5)+(6*9)+(5*8)+(4*4)+(3*6)+(2*8)+(1*7)=186
186 % 10 = 6
So 59846-87-6 is a valid CAS Registry Number.

Synthesis and reactivity of β-amino α,β-unsaturated ketones and esters using K-10 montmorillonite

Braibante,Braibante,Missio,Andricopulo

, p. 898 - 900 (2007/10/02)

A series of β-amino α,β-unsaturated ketones 3a-f and esters 3g-l may be conveniently prepared by dispersing ammonia (NH4OH solution), primary amines and 1,3-diketones or 1,3-keto esters on K-10 montmorillonite without solvent. This procedure was also applicable to the reactions of 3a and 3g with phenyl isocyanate and phenyl isothiocyanate which afford selectively the C-adducts 4a-d.
