Check Digit Verification of cas no

The CAS Registry Mumber 325147-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,5,1,4 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 325147-65:
(8*3)+(7*2)+(6*5)+(5*1)+(4*4)+(3*7)+(2*6)+(1*5)=127
127 % 10 = 7
So 325147-65-7 is a valid CAS Registry Number.

Selective synthesis and kinetic measurement of 1:1 and 2:2 cyclic compounds containing 1,4,7,10-tetraazacyclododecane and azobenzene units

Wei,Tomohiro,Kodaka,Okuno

, p. 8979 - 8987 (2000)

1:1 cyclic compounds 8a-c (51-55%) and 2:2 cyclic compounds 9a-c (20-49%) containing 1,4,7,-10-tetraazacyclododecane (cyclen) and azobenzene units were selectively synthesized under UV irradiation (330 nm ?, ΔH?, and ΔS?) of 8a-c and 9a-c were studied in nonpolar media (benzene) and polar media (methanol). The cis to trans isomerization rates in the dark for these cyclic compounds increase with ring size or structural flexibility (8a ? dominates ΔG? in cyclic compounds.
