87927-72-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87927-72-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,2 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87927-72:
(7*8)+(6*7)+(5*9)+(4*2)+(3*7)+(2*7)+(1*2)=188
188 % 10 = 8
So 87927-72-8 is a valid CAS Registry Number.

Novel Desulphurization of 1,3-Disubstituted Thioureas by Superoxide Anion (O2*-): One-step Synthesis of 1,2,3-Trisubstituted Guanidines from 1,3-Disubstituted Thioureas
Kim,Yong Hae,Yon, Gyu Hwan
, p. 715 - 716 (1983)
Treatment of 1,3-diarylthioureas with superoxide anion (O2*-) at 20 deg C in tetrahydrofuran or acetonitrile resulted in the formation of 1,2,3-triarylguanidines in excellent yields.
