Check Digit Verification of cas no
The CAS Registry Mumber 18896-73-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,9 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18896-73:
(7*1)+(6*8)+(5*8)+(4*9)+(3*6)+(2*7)+(1*3)=166
166 % 10 = 6
So 18896-73-6 is a valid CAS Registry Number.

Minute synthesis of electrophilic alkenes under microwave irradiation
Ayoubi,Texier-Boullet,Hamelin
, p. 258 - 260 (2007/10/02)
Condensation of carbonyl derivatives 2 with active methylene compounds 1 is efficiently achieved, within 3 to 15 minutes under microwave irradiation by a solvent free reaction in the presence of carefully adjusted amounts of piperidine leading to Knocvenagel products 3 in good to excellent yields.
