Check Digit Verification of cas no

The CAS Registry Mumber 1438433-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,4,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1438433-40:
(9*1)+(8*4)+(7*3)+(6*8)+(5*4)+(4*3)+(3*3)+(2*4)+(1*0)=159
159 % 10 = 9
So 1438433-40-9 is a valid CAS Registry Number.

Zinc-mediated chain extension reaction of o-phenolic-l,3-diketone to o-phenolic-l,4-diketone

Liu, Hui-Fang,Meng, Ling-Guo,Hao, Xiao-Li,Qiao-Lin,Li, Jian-Fa,Xue, Song

, p. 216 - 222 (2013/07/26)

A simple methodology has been developed for the synthesis of o-phenolic-l,4-diketones from the o-phenolicl, 3-diketones. The reaction performed in the presence of organozinc reagents under mild conditions afforded the products l,4-diketones in moderate yields.
