Check Digit Verification of cas no

The CAS Registry Mumber 295343-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,5,3,4 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 295343-51:
(8*2)+(7*9)+(6*5)+(5*3)+(4*4)+(3*3)+(2*5)+(1*1)=160
160 % 10 = 0
So 295343-51-0 is a valid CAS Registry Number.

Light-Activated Sensitive Probes for Amine Detection

Valderrey, Virginia,Bonasera, Aurelio,Fredrich, Sebastian,Hecht, Stefan

, p. 1914 - 1918 (2017/02/05)

Our new, simple, and accurate colorimetric method is based on diarylethenes (DAEs) for the rapid detection of a wide range of primary and secondary amines. The probes consist of aldehyde- or ketone-substituted diarylethenes, which undergo an amine-induced decoloration reaction, selectively to give the ring-closed isomer. Thus, these probes can be activated at the desired moment by light irradiation, with a sensitivity that allows the detection of amines at concentrations as low as 10?6m in solution. In addition, the practical immobilization of DAEs on paper makes it possible to detect biogenic amines, such as cadaverine, in the gas phase above a threshold of 12 ppbv within 30 seconds.
