Check Digit Verification of cas no

The CAS Registry Mumber 1519005-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,9,0,0 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1519005-66:
(9*1)+(8*5)+(7*1)+(6*9)+(5*0)+(4*0)+(3*5)+(2*6)+(1*6)=143
143 % 10 = 3
So 1519005-66-3 is a valid CAS Registry Number.

Unconventional stereoselective one-pot synthesis of Knoevenagel-type indoles via in situ condensation of iminium salts with active methylene reagents in memory of Professor Angelo Ranise

Ranise, Angelo,Lucchesini, Francesco,Caviglia, Matteo,Alfei, Silvana,Spallarossa, Andrea,Caneva, Chiara

, p. 10858 - 10868 (2013)

A simple one-pot procedure for the stereoselective synthesis of Knoevenagel-type indoles is described. The method is based on the in situ reaction of indole iminium salts (four of them are fully characterized) with acyclic symmetrical and unsymmetrical active methylene reagents in the presence of triethylamine. In general, the overall yields are moderate to good. Some of relevant reaction parameters and steric effects affecting stereoselectivity are discussed.
