Check Digit Verification of cas no

The CAS Registry Mumber 1563174-08-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,3,1,7 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1563174-08:
(9*1)+(8*5)+(7*6)+(6*3)+(5*1)+(4*7)+(3*4)+(2*0)+(1*8)=162
162 % 10 = 2
So 1563174-08-2 is a valid CAS Registry Number.

One-pot synthesis of sulfonyl (E)-stilbenes by nitrobenzene-mediated dimerizative desulfonation of benzylic sulfones

Chang, Meng-Yang,Chen, Yi-Chia,Lin, Shin-Ying,Chan, Chieh-Kai

, p. 1740 - 1747 (2014)

A facile one-pot synthetic route for preparing sulfonyl (E)-stilbenes 4 is developed. The efficient route is realized by a nitrobenzene (PhNO 2)-mediated dimerizative desulfonation of benzylic sulfones 3 in the presence of sodium hydride (NaH) in good yields. Some synthetic investigations of sulfonyl stilbenes 4 are also examined.
