856111-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 856111-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,1,1 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 856111-34:
(8*8)+(7*5)+(6*6)+(5*1)+(4*1)+(3*1)+(2*3)+(1*4)=157
157 % 10 = 7
So 856111-34-7 is a valid CAS Registry Number.

An efficient preparation of 1-phenylsulfonylindolyl methyl sulfoxides using KF/m-CPBA
Mohanakrishnan, Arasambattu K.,Ramesh, Neelamegam
, p. 4231 - 4233 (2007/10/03)
A variety of 1-phenylsulfonylindolylmethyl sulfides are selectively oxidized to the corresponding sulfoxides using a hitherto unexplored KF/m-CPBA system. A major advantage is the absence of over-oxidation.
