Check Digit Verification of cas no

The CAS Registry Mumber 1270038-98-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,0,0,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1270038-98:
(9*1)+(8*2)+(7*7)+(6*0)+(5*0)+(4*3)+(3*8)+(2*9)+(1*8)=136
136 % 10 = 6
So 1270038-98-6 is a valid CAS Registry Number.

Asymmetric syntheses of highly functionalized bicyclo [2.2.2] octene derivatives

Iwatsu, Masafumi,Urabe, Daisuke,Inoue, Masayuki

, p. 491 - 504 (2013/08/23)

Highly functionalized bicyclo[2.2.2]octene derivatives bearing two quaternary carbon centers were synthesized in an asymmetric fashion. The key transformations were the regioselective Diels-Alder reaction between 3,6-dimethyl-o-quinone monoacetal and 1,1-diethoxyethylene and the subsequent enzymatic resolution. The optically active bicyclo[2.2.2]octene derivatives obtained should serve as versatile chiral building blocks for highly functionalized natural products such as ryanodine.
