677022-11-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 677022-11-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,7,0,2 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 677022-11:
(8*6)+(7*7)+(6*7)+(5*0)+(4*2)+(3*2)+(2*1)+(1*1)=156
156 % 10 = 6
So 677022-11-6 is a valid CAS Registry Number.

Formal enantioselective [4+3] cycloaddition by a tandem Diels-Alder reaction/ring expansion
Dai, Xing,Davies, Huw M. L.
, p. 2449 - 2456 (2007/10/03)
The tandem Diels-Alder reaction/ring expansion between cyclopentadiene and unsaturated aldehydes is a highly stereoselective process for the synthesis of bicyclo[3.2.1]octenones, the formal products of a [4+3] cycloaddition. When the initial cycloaddition
