Check Digit Verification of cas no

The CAS Registry Mumber 67092-69-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,0,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67092-69:
(7*6)+(6*7)+(5*0)+(4*9)+(3*2)+(2*6)+(1*9)=147
147 % 10 = 7
So 67092-69-7 is a valid CAS Registry Number.

Selective N1-alkylation of 3,4-dihydropyrimidin-2(1H)-ones using Mitsunobu-type conditions

Dallinger, Doris,Kappe, C. Oliver

, p. 1901 - 1903 (2007/10/03)

The regioselective N1-alkylation of 3,4-dihydropyrimidin-2(1H)-ones via Mitsunobu reaction is reported. Using the highly reactive Mitsunobu coupling reagent combination N,N,N′,N′-tetramethylazodicarboxamide/tributylphosphine (TMAD-TBP) and a set of primary alcohols a small library of N1-alkylated dihydropyrimidones is obtained in good to excellent yields.
