1123754-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1123754-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,7,5 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1123754-19:
(9*1)+(8*1)+(7*2)+(6*3)+(5*7)+(4*5)+(3*4)+(2*1)+(1*9)=127
127 % 10 = 7
So 1123754-19-7 is a valid CAS Registry Number.

experimental part, p. 2018 - 2027 (2009/08/07)
Two stereoselective routes were developed to synthesize optically pure IBR2 analogues 1-16. The first features addition of N-Boc-3-bromoindole 26 to the sulfinamide 25, providing a 1:1 ratio of the separable diasteroisomers 27 and 28 in good yield. In a s
