121691-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121691-99-4 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 121691-99:
(8*1)+(7*2)+(6*1)+(5*6)+(4*9)+(3*1)+(2*9)+(1*9)=124
124 % 10 = 4
So 121691-99-4 is a valid CAS Registry Number.

, 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
