Check Digit Verification of cas no
The CAS Registry Mumber 89129-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,2 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89129-66:
(7*8)+(6*9)+(5*1)+(4*2)+(3*9)+(2*6)+(1*6)=168
168 % 10 = 8
So 89129-66-8 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF 4,4-DIFLUORO-3-OXOBUTANOIC ACID ESTERS
-
Page/Page column 7-8, (2010/02/15)
The present invention relates to a process for the preparation of a compound of the formula (I), wherein R is C1-12 alkyl, by the contact of a compound of the general formula (II) , wherein R1 and R2 are each, independently, C1-12 alkyl; or R1 and R2 join together with the nitrogen atom to which they are attached to form an alicyclic amine ring containing 4 to 7 carbon atoms or a morpholine ring, with an acetic acid ester of the general formula (III) CH3COOR, wherein R is as defined under formula (I), in the presence of a base.
