Check Digit Verification of cas no
The CAS Registry Mumber 4748-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4748-80:
(6*4)+(5*7)+(4*4)+(3*8)+(2*8)+(1*0)=115
115 % 10 = 5
So 4748-80-5 is a valid CAS Registry Number.

Redox neutral [4+2] benzannulation of dienals and tertiary enaminones for benzaldehyde synthesis
Yang, Lu,Wei, Li,Wan, Jie-Ping
supporting information, p. 7475 - 7478 (2018/07/13)
By employing the featured amine elimination of tertiary enaminones as a key transformation, cascade reactions of dienals and tertiary enaminones involving [4+2] annulation, Hofmann-like amine elimination and aromatization are devised for benzaldehyde synthesis. This method is of particular interest in providing benzaldehydes containing an electron withdrawing group at the C3 position which are hard to access by previous methods for benzaldehyde synthesis.
