1133960-10-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1133960-10-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,9,6 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1133960-10:
(9*1)+(8*1)+(7*3)+(6*3)+(5*9)+(4*6)+(3*0)+(2*1)+(1*0)=127
127 % 10 = 7
So 1133960-10-7 is a valid CAS Registry Number.

Synthesis of 5-amino- and 4-hydroxy-2-phenylsulfonylmethylpiperidines
Masse, Julien,Langlois, Nicole
experimental part, p. 417 - 432 (2009/09/06)
Suitable protected 5-amino- and 4-hydroxy-2-phenylsulfonylmethylpiperidines were synthesized from functionalized N-benzyloxycarbonylpiperidin-l-ones through the opening of lactam ring by methyl phenyl sulfone carbanion followed by reductive aminocyclization.
