1341196-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1341196-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,1,9 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1341196-81:
(9*1)+(8*3)+(7*4)+(6*1)+(5*1)+(4*9)+(3*6)+(2*8)+(1*1)=143
143 % 10 = 3
So 1341196-81-3 is a valid CAS Registry Number.

Sulfone chemistry for the synthesis of C-branched pyrrolidines
Flores, Mari F.,Garcia, Pilar,Garrido, Narciso M.,Marcos, Isidro S.,Sanz, Francisca,Diez, David
, p. 1467 - 1472 (2011/11/12)
The synthesis of a C-branched homopyrrolidinol has been achieved by making use of the reactivity of the sulfone group in four different ways. The stereochemistry of the two compounds has been established by X-ray diffraction analysis.
