Check Digit Verification of cas no
The CAS Registry Mumber 105-11-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105-11:
(5*1)+(4*0)+(3*5)+(2*1)+(1*1)=23
23 % 10 = 3
So 105-11-3 is a valid CAS Registry Number.

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.
