Check Digit Verification of cas no
The CAS Registry Mumber 146058-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,0,5 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146058-82:
(8*1)+(7*4)+(6*6)+(5*0)+(4*5)+(3*8)+(2*8)+(1*2)=134
134 % 10 = 4
So 146058-82-4 is a valid CAS Registry Number.

Thieno[3,4-b]pyrazines: Synthesis, structure, and reactivity
Kenning, Don D.,Mitchell, Kari A.,Calhoun, Tessa R.,Funfar, Melanie R.,Sattler, Daniel J.,Rasmussen, Seth C.
, p. 9073 - 9076 (2002)
A general synthetic route has been developed for the efficient preparation of 2,3-disubstituted thieno[3,4-b]-pyrazines. These methods eliminate problems in the preparation of the precursor 3,4-diaminothiophene and utilize α-diones prepared through the reaction of the appropriate organocuprates with oxalyl chloride. This combination allows the convenient preparation of thieno[3,4-b]pyrazine and its 2,3-disubstituted analogues (where substituent = methyl, hexyl, octyl, decyl, dodecyl, and phenyl) in high yield. Characterization of the structure and reactivity of this class of compounds is also described, including the results of structural, electrochemical, and pKa studies.
