Check Digit Verification of cas no

The CAS Registry Mumber 1027169-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,1,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027169-53:
(9*1)+(8*0)+(7*2)+(6*7)+(5*1)+(4*6)+(3*9)+(2*5)+(1*3)=134
134 % 10 = 4
So 1027169-53-4 is a valid CAS Registry Number.

Synthesis of 2,5-dihalothiazole-4-carboxylates

Okonya, John F,Al-Obeidi, Fahad

, p. 7051 - 7053 (2002)

An efficient synthesis of 2,5-dihalothiazole-4-carboxylates has been described. Halogenation of aminothiazole carboxylate with NBS or NCS and subsequent diazotization with isoamyl nitrite and halogenation with CuBr2, CuCl2 or CH2I2 provided the corresponding diahalothiazole derivatives. The four-step process described is amenable to scale-up and requires no chromatographic purification in all the steps.
