Check Digit Verification of cas no
The CAS Registry Mumber 18436-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,3 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18436-61:
(7*1)+(6*8)+(5*4)+(4*3)+(3*6)+(2*6)+(1*1)=118
118 % 10 = 8
So 18436-61-8 is a valid CAS Registry Number.

Indolenium salts, which readily undergo cleavage in aqueous alkali to give a monosubstituted acetylene and 1,3,3-trimethyl-2-oxindole, are formed when acyl derivatives of the Fischer base are heated with phosphorus oxychloride.Various aryl- and hetarylacetylenes can be conveniently obtained by this method.
