Check Digit Verification of cas no

The CAS Registry Mumber 109649-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,4 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109649-84:
(8*1)+(7*0)+(6*9)+(5*6)+(4*4)+(3*9)+(2*8)+(1*4)=155
155 % 10 = 5
So 109649-84-5 is a valid CAS Registry Number.

Hydroxyl substitutional effect on selective synthesis of CIS, trans stilbenes and 3-arylcoumarins through perkin condensation

Xiao, Chun-Fen,Zou, Yong,Du, Jian-Li,Sun, Hong-Yi,Liu, Xian-Ke

experimental part, p. 1243 - 1258 (2012/04/04)

The substitutional effect in the selective synthesis of cis, trans stilbenes and 3-arylcoumarins has been described. The regio- and geometrical selectivity for synthesis of stilbene derivatives under the Perkin strategy strongly depends on the presence or absence of hydroxyl group as well as their positions in the phenyl ring. As a result, practical synthetic strategies were established for preparing various natural stilbenes including combretastatin A-4, pterostilbene, and resveratrol with satisfactory yields (49.2-63.7%).
