Check Digit Verification of cas no

The CAS Registry Mumber 104936-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,3 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104936-69:
(8*1)+(7*0)+(6*4)+(5*9)+(4*3)+(3*6)+(2*6)+(1*9)=128
128 % 10 = 8
So 104936-69-8 is a valid CAS Registry Number.

Novel process for synthesis of 1,2,4-triazoles: Ytterbium triflate-catalyzed cyclization of hydrazonyl chlorides with nitriles

Su, Weike,Yang, Dianwen,Li, Jianjun

, p. 1435 - 1440 (2005)

A series of 1,3,5-trisubstituted 1,2,4-triazoles were synthesized via the intermolecular cyclization of hydrazonyl chlorides with nitriles catalyzed by ytterbium triflate [Yb(OTf)3]. The amount of catalysis was discussed and Yb(OTf)3 could be reused without loss of activity. Copyright Taylor & Francis, Inc.
