Check Digit Verification of cas no

The CAS Registry Mumber 1383815-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,8,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1383815-21:
(9*1)+(8*3)+(7*8)+(6*3)+(5*8)+(4*1)+(3*5)+(2*2)+(1*1)=171
171 % 10 = 1
So 1383815-21-1 is a valid CAS Registry Number.

Catalytic guanylation of aliphatic, aromatic, heterocyclic primary and secondary amines using nanocrystalline zinc(II) oxide

Kantam, M. Lakshmi,Priyadarshini,Amal Joseph,Srinivas,Vinu,Klabunde,Nishina, Yuta

, p. 5730 - 5737 (2012)

Nanocrystalline ZnO was found to be a highly efficient heterogeneous catalyst for the guanylation of amines with various carbodiimides to afford N,N′,N″-trisubstituted guanidines in excellent yields. Structurally divergent aliphatic, aromatic, heterocyclic primary and secondary amines were converted to the corresponding N,N′,N″-trisubstituted guanidines using optimal conditions. The catalyst was easy to handle even under atmospheric conditions and can be easily recovered by centrifugation and reused for five cycles with consistent activity.
