99967-50-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99967-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,6 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99967-50:
(7*9)+(6*9)+(5*9)+(4*6)+(3*7)+(2*5)+(1*0)=217
217 % 10 = 7
So 99967-50-7 is a valid CAS Registry Number.

The use of the Mitsunobu reaction in preparation of chiral synthons for macrocyclic frameworks
Gryko, Daniel T.,Piatek, Piotr,Salanski, Piotr,Jurczak, Janusz
, p. 1771 - 1778 (2007/10/03)
The Mitsunobu reaction was used for the synthesis of chiral diesters 2 and 6 and chiral diamine 4. Five new chiral macrocyclic bisamides were synthesized, starting from these precursors.
