Check Digit Verification of cas no

The CAS Registry Mumber 1574407-90-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,4,4,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1574407-90:
(9*1)+(8*5)+(7*7)+(6*4)+(5*4)+(4*0)+(3*7)+(2*9)+(1*0)=181
181 % 10 = 1
So 1574407-90-1 is a valid CAS Registry Number.

Tandem ruthenium-catalyzed transfer-hydrogenative cyclization/ intramolecular diels-alder reaction of enediynes affording dihydrocoumarin-fused polycycles

Yamamoto, Yoshihiko,Matsui, Kazuma,Shibuya, Masatoshi

, p. 1806 - 1809 (2014/04/17)

A tandem transfer-hydrogenative cyclization/intramolecular Diels-Alder reaction of enediyne substrates, containing 1,6-diyne, acrylate dienophile, and phenol tether moieties, was successfully accomplished using the combination of a cationic ruthenium complex, [CpRu(AN)3]PF6 (1b, Cp = ?5-C5H5, AN = MeCN), as the catalyst and a Hantzsch ester as the H2 surrogate to afford interesting dihydrocoumarin-fused polycyclic products as single diastereomers.
