Check Digit Verification of cas no

The CAS Registry Mumber 31638-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,3 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31638-89:
(7*3)+(6*1)+(5*6)+(4*3)+(3*8)+(2*8)+(1*9)=118
118 % 10 = 8
So 31638-89-8 is a valid CAS Registry Number.

Synthesis of a C3-symmetric tris-imine via dynamic covalent bond formation between a trialdehyde and a triamine

Nakada, Keiko,Kondo, Seiya,Matsumoto, Yoshiteru,Yamanaka, Masamichi

, p. 4612 - 4616 (2017)

Dynamic covalent chemistry is an effective technique for the preparation of complex organic compounds. We succeeded in synthesizing a cage-shaped compound through the aggregation of two types of functional molecules. More specifically, a tris-imine 5 was quantitatively obtained by reacting a C3-symmetric trialdehyde 1 with a triamine 4 in acetonitrile in the presence of a trifluoroacetic acid catalyst. We also achieved the synthesis of the corresponding triamine 9 and the acetylated derivative 10 through reduction of the tris-imine C[dbnd]N double bonds and subsequent acetylation.
