Check Digit Verification of cas no

The CAS Registry Mumber 1258239-14-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,3 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1258239-14:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*3)+(3*9)+(2*1)+(1*4)=163
163 % 10 = 3
So 1258239-14-3 is a valid CAS Registry Number.

Asymmetric cyclopropanation of alkenes with dimethyl diazomalonate catalyzed by chiral diene-rhodium complexes

Nishimura, Takahiro,Maeda, Yuko,Hayashi, Tamio

supporting information; experimental part, p. 7324 - 7327 (2010/11/18)

Chiral tridentate ligand : A chiral dienerhodium complex (1; see scheme) was found to catalyze the intermolecular asymmetric cyclopropanation of alkenes with dimethyl diazomalonate to give 1,1-cyclopropane diesters in good yields and with high enantioselectivity.
