Check Digit Verification of cas no

The CAS Registry Mumber 1226993-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,9,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1226993-91:
(9*1)+(8*2)+(7*2)+(6*6)+(5*9)+(4*9)+(3*3)+(2*9)+(1*1)=184
184 % 10 = 4
So 1226993-91-4 is a valid CAS Registry Number.

A new fluorescent sensor for the detection of pyrophosphate based on a tetraphenylethylene moiety

Park, Chuneung,Hong, Jong-In

, p. 1960 - 1962 (2010)

We have developed a new fluorescent sensor 1-2Zn based on a tetraphenylethylene (TPE) moiety for the detection of PPi. This TPE-based chemosensor showed 'turn-on' fluorescence emission according to the concentration of PPi. The fluorescence enhancement upon binding of PPi to 1-2Zn resulted from the restriction of intramolecular rotation of phenyl rings in 1-2Zn.
