Check Digit Verification of cas no
The CAS Registry Mumber 189877-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,7 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189877-84:
(8*1)+(7*8)+(6*9)+(5*8)+(4*7)+(3*7)+(2*8)+(1*4)=227
227 % 10 = 7
So 189877-84-7 is a valid CAS Registry Number.

Attempted perilithiation of 1-naphthamides with their 2-positions blocked leads only to nucleophilic attack on the aromatic ring, but perilithiation of naphthalenes bearing 1-substituents such as -NMe2 or CH2NMe2 allows the synthesis of 8-substituted-1-naphthamldes. The 8- CH2NMe2 substituents can be converted to carbonyl groups by Polonovski reactions; other 8-substituents may be introduced by using naphthalic anhydride as a starting material.
