91531-32-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91531-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,3 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91531-32:
(7*9)+(6*1)+(5*5)+(4*3)+(3*1)+(2*3)+(1*2)=117
117 % 10 = 7
So 91531-32-7 is a valid CAS Registry Number.

Ortho-sulfenylation of N,N-dimethyl-1-phenylethylamine and oxidation of the resultant sulfides
Shimazaki,Takahashi,Komatsu,Ohta,Kajii,Kodama
, p. 555 - 557 (2007/10/02)
The ortho-lithiation of chiral N,N-dimethyl-1-phenylethylamine (1) followed by sulfenylation and oxidation of the resulting sulfides afforded chiral sulfoxides 3 and 4. Use of sodium perborate as the oxidant gave the highest de.
