Check Digit Verification of cas no

The CAS Registry Mumber 937740-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,7,4 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 937740-19:
(8*9)+(7*3)+(6*7)+(5*7)+(4*4)+(3*0)+(2*1)+(1*9)=197
197 % 10 = 7
So 937740-19-7 is a valid CAS Registry Number.

Facile synthesis of (±)-paeonilide

Du, Yuguo,Liu, Jun,Linhardt, Robert J.

, p. 3952 - 3954 (2008/02/01)

(Chemical Equation Presented) (±)-Paeonilide, a novel monoterpenoid metabolite from the roots of Paeonia delavayi showing anti-platelet activating factor activity, is convergently synthesized in five steps with 59% overall yield. The application of benzoyl peroxide-promoted radical addition of unsaturated ester to aldehyde and subsequent topologically favored cyclization greatly simplified the synthesis.
