Check Digit Verification of cas no

The CAS Registry Mumber 690656-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,6,5 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 690656-90:
(8*6)+(7*9)+(6*0)+(5*6)+(4*5)+(3*6)+(2*9)+(1*0)=197
197 % 10 = 7
So 690656-90-7 is a valid CAS Registry Number.

A novel enantioselective (2Z)-alk-2-enylation of aldehydes via an allyl-transfer reaction from chiral allyl donors prepared from (+)-isomenthone

Nokami, Junzo,Nomiyama, Kenta,Shafi, Siddiqi M.,Kataoka, Kazuhide

, p. 1261 - 1264 (2007/10/03)

A highly enantioselective (22)-alk-2-enylation of aldehydes was successfully achieved by an allyl-transfer reaction from a chiral allyl donor, which was easily obtained by separation of a diastereomeric mixture of the corresponding homoallylic alcohol γ-adducts derived from (+)-isomenthone with alk-2-enylmagnesium chloride.
