Check Digit Verification of cas no

The CAS Registry Mumber 151872-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,8,7 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151872-43:
(8*1)+(7*5)+(6*1)+(5*8)+(4*7)+(3*2)+(2*4)+(1*3)=134
134 % 10 = 4
So 151872-43-4 is a valid CAS Registry Number.

Reaction of C60 with Inactive Secondary Amines and Aldehydes and the Cu(OAc)2-Promoted Regioselective Intramolecular C-H Functionalization of the Generated Fulleropyrrolidines

, p. 11201 - 11209 (2016/11/28)

The thermal reaction of C60 with aromatic aldehydes and inactive secondary amines for the stereoselective synthesis of trans-1,2,5-trisubstituted fulleropyrrolidines has been developed. Moreover, when an o-hydroxyl group was located at the phenyl ring of the generated fulleropyrrolidines, the Cu(OAc)2-promoted regioselective intramolecular C-O coupling reaction occurred to generate unique tricycle-fused fullerene derivatives.
