1357155-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1357155-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,1,5 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1357155-44:
(9*1)+(8*3)+(7*5)+(6*7)+(5*1)+(4*5)+(3*5)+(2*4)+(1*4)=162
162 % 10 = 2
So 1357155-44-2 is a valid CAS Registry Number.

Organocatalytic asymmetric synthesis of 3-difluoroalkyl 3-hydroxyoxindoles
Liu, Yun-Lin,Zhou, Jian
supporting information; experimental part, p. 1919 - 1921 (2012/03/11)
We report the first example of highly enantioselective organocatalytic synthesis of 3-difluoroalkyl substituted 3-hydroxyoxindoles. The total synthesis of the difluoro analogue of convolutamydine E was achieved by this method.
