Check Digit Verification of cas no

The CAS Registry Mumber 882525-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,5,2 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 882525-07:
(8*8)+(7*8)+(6*2)+(5*5)+(4*2)+(3*5)+(2*0)+(1*7)=187
187 % 10 = 7
So 882525-07-7 is a valid CAS Registry Number.

Regioselective synthesis of 4-alkylpyridines from pyridine and aldehydes via dipole reversal process of 1,4-dihydropyridine phosphonate

Lee, Phil Ho,Lee, Kooyeon,Shim, Jun Hwan,Lee, Seong Guk,Kim, Sundae

, p. 777 - 784 (2007/10/03)

4-Alkylation of pyridine has been accomplished by the reaction of ylides, derivated from 1,4-dihydropyridine phosphonate via phosphonioalkoxycarbonylation of pyridine with aldehydes and subsequent elimination of diisopropyl phosphate followed by aromatization with potassium tert-butoxide.
