Check Digit Verification of cas no

The CAS Registry Mumber 657401-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,7,4,0 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 657401-96:
(8*6)+(7*5)+(6*7)+(5*4)+(4*0)+(3*1)+(2*9)+(1*6)=172
172 % 10 = 2
So 657401-96-2 is a valid CAS Registry Number.

Olefin Metathesis: Remote Substituents Governing the Stereoselectivity of 11-Membered-Ring Formation

Vassilikogiannakis, Georgios,Margaros, Ioannis,Tofi, Maria

, p. 205 - 208 (2007/10/03)

(Matrix presented) Stereospecific RCM reaction of 7 (R1 = Me) results in the formation of (Z)-11-membered macrocycle 9c. Cascade RCM/ROM/RCM transformation of 7 (R1 = H) affords the thermodynamically more stable spirocycle product 12.
