Check Digit Verification of cas no
The CAS Registry Mumber 188721-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,2 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 188721-64:
(8*1)+(7*8)+(6*8)+(5*7)+(4*2)+(3*1)+(2*6)+(1*4)=174
174 % 10 = 4
So 188721-64-4 is a valid CAS Registry Number.

Hydrohalogenation of 1,4-Benzoquinone Mono- and Bis(O-acyloximes)
Avdeenko,Glinyanaya
, p. 1154 - 1159 (2007/10/03)
Hydrohalogenation of 1,4-benzoquinone O-acyloximes involves intermediate formation of corresponding 1,4-benzoquinone monooximes and hydroxyamino derivatives. The final hydrochlorination products are 2,6-dichloro-4-alkoxyanilines, hydrobromination yields 3,5-dibromo-4-aminophenol as the final product. O-Acyl- and O,O′-diacyl-1,4-benzoquinone dioximes do not undergo hydrohalogenation.
