87486-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87486-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,8 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87486-38:
(7*8)+(6*7)+(5*4)+(4*8)+(3*6)+(2*3)+(1*8)=182
182 % 10 = 2
So 87486-38-2 is a valid CAS Registry Number.

, p. 919 - 923 (2007/10/02)
The hydrohalides of 2-sec-aminoalkanenitriles on treatment with oxalyl halides in o-dichlorobenzene at 80-100° give 3,5-dihalo-2(1H)-pyrazinones, of which the 3-halo substituent is easily replaced by nucleophiles. A reaction mechanism for the pyrazinone s
