198204-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 198204-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,2,0 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 198204-40:
(8*1)+(7*9)+(6*8)+(5*2)+(4*0)+(3*4)+(2*4)+(1*0)=149
149 % 10 = 9
So 198204-40-9 is a valid CAS Registry Number.

, p. 5102 - 5107 (2008/10/08)
Tris[2-(dimethylamino)phenyl]silane and -germane compounds (1 and 2) were synthesized and characterized by X-ray crystallography. Three 2-(dimethylamino)phenyl groups in the hydrosilane (1a) and hydrogermane (1b) encapsulate the hydrogen atom bonded to si
