Check Digit Verification of cas no

The CAS Registry Mumber 328971-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,8,9,7 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 328971-29:
(8*3)+(7*2)+(6*8)+(5*9)+(4*7)+(3*1)+(2*2)+(1*9)=175
175 % 10 = 5
So 328971-29-5 is a valid CAS Registry Number.

Synthesis of 5,5'-(arylmethylene)bis(pyrimidinone) derivatives in aqueous media

Shi, Da-Qing,Niu, Li-Hui,Zhuang, Qi-Ya

, p. 719 - 721 (2008)

The condensation and addition reactions of aromatic aldehydes and 4,6-dihydroxypyrimidine or 2,4-dihydroxy-6-aminopyrimidine in water in the presence of triethylbenzylammonium chloride (TEBAC) afford a one-pot synthesis of 5,5'-(arylmethylene)bis[6-hydroxypyrimidine-4(3H)-one]s and 5,5'-(arylmethylene)bis[6-aminopyrimidine-2,4 (1H,3H)-dione]s. These compounds were characterised by elemental analysis and IR and 1H NMR spectra and further confirmed by a single crystal X-ray diffraction analysis.
