Check Digit Verification of cas no

The CAS Registry Mumber 1537890-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,7,8,9 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1537890-05:
(9*1)+(8*5)+(7*3)+(6*7)+(5*8)+(4*9)+(3*0)+(2*0)+(1*5)=193
193 % 10 = 3
So 1537890-05-3 is a valid CAS Registry Number.

Stereoselective addition of dialkyl phosphites to di-salicylaldimines bearing the (R,R)-1,2-diaminocyclohexane moiety

Lewkowski, Jaros?aw,Tokarz, Pawe?,Lis, Tadeusz,?lepokura, Katarzyna

, p. 810 - 816 (2014/01/23)

The addition of dialkyl phosphites to the azomethine bond of N,N′-disalicylidene-1,2-diaminocyclohexane imines, catalyzed by sodium hydride led to bis-aminophosphonates in a high diastereoselectivity. One of the bis-aminophosphonates was analyzed by X-ray
