Check Digit Verification of cas no

The CAS Registry Mumber 1329116-26-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,9,1,1 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1329116-26:
(9*1)+(8*3)+(7*2)+(6*9)+(5*1)+(4*1)+(3*6)+(2*2)+(1*6)=138
138 % 10 = 8
So 1329116-26-8 is a valid CAS Registry Number.

Convenient one-pot synthesis of 3-aryl-2H-chromene- 4-carbonitriles via a tandem O-alkylationknoevenagel condensation

Chen, Yanhong,Xiang, Haoyue,Xie, Yuyuan,Yang, Chunhao

experimental part, p. 1355 - 1361 (2011/06/27)

3-Aryl-2H-chromene-4-carbonitriles were synthesized through one-pot tandem reaction of easily available 2-(2-hydroxyphenyl)acetonitrile (1) and 2-bromo-1-arylethanones (2) under the condition of K2CO 3/dioxane. These functionalized chromenes could be useful building-blocks for estrogen receptor ligands and other related heterocycles.
