Check Digit Verification of cas no

The CAS Registry Mumber 947769-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,7,7,6 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 947769-31:
(8*9)+(7*4)+(6*7)+(5*7)+(4*6)+(3*9)+(2*3)+(1*1)=235
235 % 10 = 5
So 947769-31-5 is a valid CAS Registry Number.

Two-photon absorption enhancement induced by aggregation due to intermolecular hydrogen bonding in V-shaped 2-hydroxypyrimidine derivatives

Liu, Zijun,Shao, Pin,Huang, Zhenli,Liu, Bo,Chen, Tao,Qin, Jingui

, p. 2260 - 2262 (2008)

The aggregation of V-shaped hydroxypyrimidine derivatives is formed through an intermolecular hydrogen bond in chloroform that cannot form a hydrogen bond with the solute, giving rise to a large enhancement of the two-photon absorption and two-photon induced fluorescence. The Royal Society of Chemistry.
