Check Digit Verification of cas no
The CAS Registry Mumber 140614-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,1 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140614-11:
(8*1)+(7*4)+(6*0)+(5*6)+(4*1)+(3*4)+(2*1)+(1*1)=85
85 % 10 = 5
So 140614-11-5 is a valid CAS Registry Number.

Roth,Gygax,Frater
, p. 1045 - 1048 (2007/10/02)
By means of an intramolecular Baylis-Hillman reaction the cyclopentene derivative 1 has been formed from 2. Asymmetric induction is low. In the sixmembered ring example 9 → 10 the yield is only 17% - 23%.
