1285705-83-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1285705-83-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,5,7,0 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1285705-83:
(9*1)+(8*2)+(7*8)+(6*5)+(5*7)+(4*0)+(3*5)+(2*8)+(1*3)=180
180 % 10 = 0
So 1285705-83-0 is a valid CAS Registry Number.

Cyclization reactions of l-pyrimidinyi-3-arylthiourea derivatives with oxalyl dichloride
Oenal, Zuelbiye,Korkusuz, Elif,Ilhan, Ilhan Oezer
, p. 79 - 83 (2010)
N.N′-Disubstituted thioureas (la-g) can be cyclized by use of oxalyl dichloride to the 4,5-dioxo-2-thioxo-perhydroimidazolyl-pyrimidine-2(H)-thiones (2a-g) in good yields (50-68%). The structures of these compounds were determined by elemental analysis, I
