Check Digit Verification of cas no
The CAS Registry Mumber 135522-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,2 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135522-07:
(8*1)+(7*3)+(6*5)+(5*5)+(4*2)+(3*2)+(2*0)+(1*7)=105
105 % 10 = 5
So 135522-07-5 is a valid CAS Registry Number.

A NEW AND CONVENIENT PROCESS FOR PREPARATION OF OPTICALLY PURE ARYL 2-PYRIDYL SULFOXIDES
Shibutani, Tadao,Fujihara, Hisashi,Furukawa, Naomichi
, p. 2947 - 2948 (2007/10/02)
α-Lithiation of aryl 2-pyridyl sulfoxides, treatment with l-menthyl sulfinate, and desulfinylation with Grignard reagents gave optically pure aryl 2-pyridyl sulfoxides in moderate yields.
