Check Digit Verification of cas no

The CAS Registry Mumber 666856-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,8,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 666856-34:
(8*6)+(7*6)+(6*6)+(5*8)+(4*5)+(3*6)+(2*3)+(1*4)=214
214 % 10 = 4
So 666856-34-4 is a valid CAS Registry Number.

Enantioselective synthesis of the C-14 to C-5 cyclopentane segment of jatrophane diterpenes

Helmboldt, Hannes,Rehbein, Julia,Hiersemann, Martin

, p. 289 - 292 (2004)

The enantioselective synthesis of the C-14 to C-5 cyclopentane segment of jatrophane diterpenes is reported. An Evans aldol addition, a Horner-Wadsworth-Emmons olefination and a thermal intramolecular carbonyl ene reaction of an α-keto ester served as key C/C-connecting transformations.
