The CAS Registry Mumber 749249-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,4 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 749249-58:
(8*7)+(7*4)+(6*9)+(5*2)+(4*4)+(3*9)+(2*5)+(1*8)=209
209 % 10 = 9
So 749249-58-9 is a valid CAS Registry Number.

Leenders, Ruben,Heeres, Jan,Vandenput, Dirk,Zijlmans, Remco,Guillemont, Jerome,Lewi, Paul

supporting information; experimental part, p. 2852 - 2854 (2010/08/05)

An optimized procedure is given for the synthesis of novel 3-(arylamino)-1,2,4-triazin-5-one building blocks from commercially available material. By employing these building blocks, a practical protocol is described for the functionalization of the 5-position of the triazine core with anilines or phenols.
