Check Digit Verification of cas no
The CAS Registry Mumber 159709-36-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,0 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159709-36:
(8*1)+(7*5)+(6*9)+(5*7)+(4*0)+(3*9)+(2*3)+(1*6)=171
171 % 10 = 1
So 159709-36-1 is a valid CAS Registry Number.

Synthesis and structures of thieno[2,3-b]thiophene incorporated [3.3]dithiacyclophanes. Enhanced first hyperpolarizability in an unsymmetrically polarized cyclophane

Dithiacyclophanes incorporating thieno[2,3-b]thiophene have been synthesized, in order to investigate the nonlinear optical properties of donor-acceptor cyclophane 7. Cyclophane 7 displayed significantly higher first hyperpolarizability β (21.6 × 10-30 esu) compared to model 10 (9.58 × 10-30esu). Relatively higher β in 7 presumably arises from an extra electron redistribution arising from through-space charge transfer, a feature lacking in 10. Moreover, the thermal decomposition temperature of 7 (300 °C) is higher than that reported for the NLO prototype DANS (295 °C).
