125113-65-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125113-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,1 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125113-65:
(8*1)+(7*2)+(6*5)+(5*1)+(4*1)+(3*3)+(2*6)+(1*5)=87
87 % 10 = 7
So 125113-65-7 is a valid CAS Registry Number.

AN INDIRECT METHOD FOR EFFECTING THE ADDITION OF METHYLMALONATE TO 2-METHYLCYCLOHEX-2-ENONE
Robbins, S. James,Wheeler, Desmond M. S.
, p. 769 - 776 (2007/10/02)
The adduct (1a) of methylmalonate and 2-methylcyclohex-2-enone (2a) is best made by adding malonate to 2a to give 1b, protecting the ketone 0 in 1b as a ketal (3b), methylation to 3a and finally removal of the ketal.
