Check Digit Verification of cas no

The CAS Registry Mumber 143121-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,2 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143121-60:
(8*1)+(7*4)+(6*3)+(5*1)+(4*2)+(3*1)+(2*6)+(1*0)=82
82 % 10 = 2
So 143121-60-2 is a valid CAS Registry Number.

Asymmetric Cyclization via Tandem Conjugate Addition by Using Metal Amide Reagents. Importance of the Folded Orientation of Two Enoate Moieties

Shida, Naomi,Uyehara, Tadao,Yamamoto, Yoshinori

, p. 5049 - 5051 (2007/10/02)

Di-(-)-menthyl nona-2,7-diene-1,9-dioate (1) is converted to (-)-menthyl 3(S)-(N-benzylamino)-2(S)-(-)-menthoxycarbonyl-1(S)-cyclohexane-1-acetate (2) with high diastereoselectivity upon treatment with the amide cuprate or zincate reagent Bn(TMS)NMLn in the presence of ZnCl2.The folded orientation of the two enoate moieties of 1 is essential for this high asymmetric cyclization via tandem conjugate addition.
