Check Digit Verification of cas no

The CAS Registry Mumber 1158681-12-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,6,8 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1158681-12:
(9*1)+(8*1)+(7*5)+(6*8)+(5*6)+(4*8)+(3*1)+(2*1)+(1*2)=169
169 % 10 = 9
So 1158681-12-9 is a valid CAS Registry Number.

Regio- and stereoselective heck α-arylation of cinnamyl alcohols

Ambrogio, Ilaria,Cacchi, Sandro,Fabrizi, Giancarlo,Goggiamani, Antonella,Sgalla, Simona

experimental part, p. 620 - 624 (2009/07/11)

The Heck reaction of cinnamyl alcohols with aryl iodides has been investigated using n-Bu4NOAc as the base in toluene. Under these conditions, the reaction affords regio- and stereoselectively (Z)-2,3-diarylallylic alcohols in moderate to good yields. Experimental evidence suggests that the observed selectivity in formation of the vinylic substitution products is kinetic in origin under these conditions and that both the base and the solvent play a key role.
