1292295-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1292295-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,2,9 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1292295-90:
(9*1)+(8*2)+(7*9)+(6*2)+(5*2)+(4*9)+(3*5)+(2*9)+(1*0)=179
179 % 10 = 9
So 1292295-90-9 is a valid CAS Registry Number.

, p. 173 - 179 (2011)
A simple and convenient one-pot synthesis of (1R,4S,6R)-4-isopropenyl-1,3, 3-trimethyl-7-oxabicyclo[4.1.0]heptan-2-one was developed consisting in a thermodynamic methylation of carvone (NaH, MeI, THF, 20°C) followed by the epoxidation with alkalinized hy
