Check Digit Verification of cas no

The CAS Registry Mumber 37819-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 37819-91:
(7*3)+(6*7)+(5*8)+(4*1)+(3*9)+(2*9)+(1*1)=153
153 % 10 = 3
So 37819-91-3 is a valid CAS Registry Number.

Potential Anticancer Agents. XXVI. Spin Labelled Nitrosoureas

Baracu, Ileana,Dobre, V.,Niculescu-Duvaz, I.

, p. 667 - 674 (2007/10/02)

In order to obtain more information about the in vivo mechanism of action of nitrosoureas, the synthesis of spin labelled nitrosoureas derived from 1-oxyl-2.2.6.6-tetramethyl-4-aminopiperidine was undertaken.The synthesis of four spin labelled ureas 4a-4d was reported as well as two spin labelled nitrosoureas: 1-methyl-3-(2'.2'.6'.6'-tetramethyl-piperidin-4'-yl-1'-oxyl)-1-nitrosourea (9a) and 1-(2'-chloroethyl)-3-(2".2".6".6"-tetramethyl-piperidin-4"-yl-1"-oxyl)-1-nitrosourea (9b).Their e.s.r. spectra were recorded.None of these compounds proved to be active against L1210.
