Check Digit Verification of cas no

The CAS Registry Mumber 1351665-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,1,6,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1351665-19:
(9*1)+(8*3)+(7*5)+(6*1)+(5*6)+(4*6)+(3*5)+(2*1)+(1*9)=154
154 % 10 = 4
So 1351665-19-4 is a valid CAS Registry Number.

Cu-Catalyzed [3 + 3] Annulation for the Synthesis of Pyrimidines via β-C(sp3)-H Functionalization of Saturated Ketones

Zhan, Jun-Long,Wu, Meng-Wei,Chen, Fei,Han, Bing

, p. 11994 - 12000 (2016)

A novel, efficient, and facile approach for the synthesis of structurally important pyrimidines has been successfully developed by Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones. This method provides a new protocol for the synthesis of pyrimidines by a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization via direct β-C(sp3)-H functionalization of saturated ketones followed by annulation with amidines.
