352015-01-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 352015-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,0,1 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 352015-01:
(8*3)+(7*5)+(6*2)+(5*0)+(4*1)+(3*5)+(2*0)+(1*1)=91
91 % 10 = 1
So 352015-01-1 is a valid CAS Registry Number.

Highly efficient chiral copper Schiff-base catalyst for asymmetric cyclopropanation of 2,5-dimethyl-2,4-hexadiene

Itagaki, Makoto,Hagiya, Koji,Kamitamari, Masashi,Masumoto, Katsuhisa,Suenobu, Katsuhiro,Yamamoto, Yohsuke

, p. 7835 - 7843 (2004)

A remarkable increase in catalytic activity is found for the asymmetric cyclopropanation of 2,5-dimethyl-2,4-hexadiene with diazoacetate by use of the chiral copper Schiff-base complexes, which are derived from substituted salicylaldehydes, chiral aminoalcohols, and copper acetate monohydrate. Furthermore, a combination of a chiral copper Schiff-base with a Lewis acid showed an increase in yield (up to 90%) and in enantioselectivity (up to 90% ee) for the asymmetric cyclopropanation of the diene with t-butyl diazoacetate at 20°C.
