202859-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 202859-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,8,5 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 202859-87:
(8*2)+(7*0)+(6*2)+(5*8)+(4*5)+(3*9)+(2*8)+(1*7)=138
138 % 10 = 8
So 202859-87-8 is a valid CAS Registry Number.

(R)-Carvone as chiral template for the synthesis of some polyols
Brabander, J. De,Kulkarni, B. A.,Garcia-Lopez, R.,Vandewalle, M.
, p. 665 - 670 (2007/10/03)
Some (4S,6R,7R) 4,6,7-trihydroxyheptyl derived building blocks have been obtained from (R)-carvone as the chiral template.A key-step is the Baeyer-Villiger oxidation of a suitable intermediate.
