Check Digit Verification of cas no

The CAS Registry Mumber 523978-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,3,9,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 523978-13:
(8*5)+(7*2)+(6*3)+(5*9)+(4*7)+(3*8)+(2*1)+(1*3)=174
174 % 10 = 4
So 523978-13-4 is a valid CAS Registry Number.

Intramolecular photoreaction of thiobarbiturates with an alkenyl or a benzyl group in their N-alkyl side chain. Regioselective synthesis of ring-fused pyrimidine derivatives through photocyclization of mono- and dithiobarbiturates

Takechi, Haruko,Takahashi, Hajime,Mahara, Reijiro,Machida, Minoru

, p. 303 - 316 (2007/10/03)

Upon irradiation, thiobarbiturates with an alkenyl (4,5) or a benzyl (14,15,21) group in their N-alkyl side chain give bi- and tri-cyclic fused pyrimidine derivatives through regioselective [2+2] photocycloaddition or Norrish type II reaction, respectively.
