140862-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140862-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,6 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 140862-29:
(8*1)+(7*4)+(6*0)+(5*8)+(4*6)+(3*2)+(2*2)+(1*9)=119
119 % 10 = 9
So 140862-29-9 is a valid CAS Registry Number.

SYNTHESIS OF HALOHYDROXYPYRAZINES AND THEIR SYNTHETIC UTILITY
Aoyagi, Yutaka,Fujiwara, Takako,Ohta, Akihiro
, p. 2407 - 2415 (2007/10/02)
Treatment of hydroxypyrazines with N-halosuccinimide (NXS; X=Cl, Br,I) in N,N-dimethylformamide (DMF) at room temperature afforded halohydroxypyrazines in good yields.Their synthetic utility was examined.
