Check Digit Verification of cas no

The CAS Registry Mumber 1093451-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,4,5 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1093451-31:
(9*1)+(8*0)+(7*9)+(6*3)+(5*4)+(4*5)+(3*1)+(2*3)+(1*1)=140
140 % 10 = 0
So 1093451-31-0 is a valid CAS Registry Number.

Regioselective synthesis of tetrasubstituted pyrroles by 1,3-dipolar cycloaddition and spontaneous decarboxylation

Kim, Yongju,Kim, Jonghoon,Park, Seung Bum

supporting information; experimental part, p. 17 - 20 (2009/08/07)

We developed a novel regioselective synthesis of tetrasubstituted pyrroles via the classic 1,3-dipolar cycloaddition of α,β-unsaturated benzofuran-3(2H)-one and azlactones (1) followed by spontaneous decarboxylation. The complete regiochemical control of tetrasubstituted pyrroles was confirmed by the orthogonal synthesis of complementary regioisomers (7a and 7b) simply by using different azlactones (1a and 1b, respectively).
