Check Digit Verification of cas no

The CAS Registry Mumber 132275-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,2,7 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132275-08:
(8*1)+(7*3)+(6*2)+(5*2)+(4*7)+(3*5)+(2*0)+(1*8)=102
102 % 10 = 2
So 132275-08-2 is a valid CAS Registry Number.

A novel and convenient synthesis of E,E-bis(styryl)sulfones and E,E-1,4-diaryl-1,3-butadienes

Ramana Reddy,Manjubhashini,Reddy,Ramana Reddy,Bhaskar Reddy

, p. 1589 - 1596 (2007/10/02)

The condensation of 2-phenylethanesulfonylacetic acid (4) with araldehydes (5) in presence of a base gave E-styryl-2-phenylethyl sulfones (6) which on dehydrogenation with DDQ (7) yielded E,E-bis-(styryl)sulfones (8). The 8 on treatment with dichlorotris(triphenyl-phosphine)ruthehium(II) catalyst resulted 1,4-diaryl-1,3-butadienes (9). The configurations of 6, 8 and 9 have been determined based on IR and 1H NMR spectral data.
