Check Digit Verification of cas no

The CAS Registry Mumber 133095-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,9 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133095-59:
(8*1)+(7*3)+(6*3)+(5*0)+(4*9)+(3*5)+(2*5)+(1*9)=117
117 % 10 = 7
So 133095-59-7 is a valid CAS Registry Number.

Palladium catalyzed cyclizations of enantiomerically pure acyclic 4-acetoxy-2,8-nonadienes: Efficient chirality transfer

Oppolzer, Wolfgang,Birkinshaw, Timothy N.,Bernardinelli, Gerald

, p. 6995 - 6998 (2007/10/02)

S-4-Acetoxy-6-aza-2,8-nonadienes 9 and 11 were subjected to Pd(0)-catalyzed cyclizations. The S,E-acetate 9 gave exclusively S,E-pyrrolidine 12, whereas the antipodal product R,E-12 was formed from the S,Z-precursor 11 (Scheme 3). X-ray-diffraction analys
