139232-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139232-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,3 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139232-40:
(8*1)+(7*3)+(6*9)+(5*2)+(4*3)+(3*2)+(2*4)+(1*0)=119
119 % 10 = 9
So 139232-40-9 is a valid CAS Registry Number.

supporting information, p. 11114 - 11118 (2013/10/22)

Tuning the organocatalyst: An unprecedented enantioselective intramolecular oxa-Michael reaction of unactivated α,β-unsaturated amides and esters catalyzed by a powerful hydrogen-bond-donating organocatalyst has been developed. Furthermore, the products obtained from this reaction have been used for the straightforward asymmetric synthesis of several natural products and biologically important compounds. Copyright
