727651-44-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 727651-44-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,6,5 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 727651-44:
(8*7)+(7*2)+(6*7)+(5*6)+(4*5)+(3*1)+(2*4)+(1*4)=177
177 % 10 = 7
So 727651-44-7 is a valid CAS Registry Number.

Efficient synthesis of pyrimidinecarbonitriles and their derivatives
Dolakova, Petra,Masojidkova, Milena,Holy, Antonin
, p. 1107 - 1115 (2008/02/08)
New approach to pyrimidinecarbonitriles was developed. Pyrimidine-4- and 6-carbonitriles were prepared by palladium-catalyzed cross-coupling reaction of iodopyrimidines with Zn(CN)2 in very good yields. The cyano group was converted into the co
