121691-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121691-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,9 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121691-97:
(8*1)+(7*2)+(6*1)+(5*6)+(4*9)+(3*1)+(2*9)+(1*7)=122
122 % 10 = 2
So 121691-97-2 is a valid CAS Registry Number.

Synthesis of the Oviposition-Deterring Pheromone (ODP) in Rhagoletis cerasi L.
Ernst, Beat,Wagner, Beatrice
, p. 165 - 171 (2007/10/02)
For the assignment of the configuration at C(8) and C(15) of the natural oviposition-deterring pheromone 1 in Rhagoletis cerasi L., the four possible stereoisomers of 1 are synthesized.By condensing the C6 building blocks (5R)-4 and (5S)-4 with the boron
