Check Digit Verification of cas no

The CAS Registry Mumber 1648931-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,8,9,3 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1648931-34:
(9*1)+(8*6)+(7*4)+(6*8)+(5*9)+(4*3)+(3*1)+(2*3)+(1*4)=203
203 % 10 = 3
So 1648931-34-3 is a valid CAS Registry Number.

Exploring the reactivity of chiral glycidic amides for their applications in synthesis of bioactive compounds

A new class of chiral sulfonium salts, derived from L- and D-methionine, has been designed and successfully employed in our laboratories for the diastereoselective synthesis of glycidic amides. The epoxy amides obtained were converted cleanly into 1,2-difunctionalized products through oxirane ring-opening reactions with different types of nucleophiles. The resulting ring-opened products represent valuable and useful building blocks for the synthesis of different bioactive products. Thus, the expedient synthesis of clavaminol H as well as the synthesis of key precursors for other bioactive compounds, for example, polyketide-derived natural products, have been achieved, demonstrating the synthetic efficiency and utility of this chemistry. The reactivity of chiral epoxy amides, efficiently prepared by a new asymmetric epoxidation methodology, has been explored through their reactions with various nucleophiles. The high regioselectivity and complete stereoselectivity observed for these ring-opening reactions were applied to the synthesis of bioactive compounds. Copyright
