Check Digit Verification of cas no

The CAS Registry Mumber 53443-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,4,4 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 53443-95:
(7*5)+(6*3)+(5*4)+(4*4)+(3*3)+(2*9)+(1*5)=121
121 % 10 = 1
So 53443-95-1 is a valid CAS Registry Number.

One-pot multistep synthesis of trisubstituted alkenes from N -tosylhydrazones and alcohols

Sha, Qiang,Wei, Yunyang

, p. 2353 - 2361 (2014/11/08)

A one-pot procedure for the synthesis of trisubstituted alkenes from N-tosylhydrazones and alcohols is reported. This procedure combines the aerobic oxidation reaction and Wittig reaction in one pot, which avoids using of environmentally toxic oxidants and isolation of the intermediates. The simple procedure makes it very attractive for the synthesis of trisubstituted alkenes when alcohols are used as starting materials. A variety of trisubstituted alkenes as well as trifluoromethyl-substituted alkenes were obtained in moderate to good yields (up to 84%) with good E-selectivity (up to 99%).
