Check Digit Verification of cas no

The CAS Registry Mumber 1385837-63-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,5,8,3 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1385837-63:
(9*1)+(8*3)+(7*8)+(6*5)+(5*8)+(4*3)+(3*7)+(2*6)+(1*3)=207
207 % 10 = 7
So 1385837-63-7 is a valid CAS Registry Number.

4-Aminopyrimidine libraries from the Ugi-Smiles reaction of thiouracil

Sidhoum, Madjid Ait,El Ka?m, Laurent,Grimaud, Laurence

, p. 5222 - 5231 (2018/05/04)

The Ugi-Smiles reaction of S-benzyl thiouracil have been exploited in several three-step sequences for the preparation of aminopyrimidine libraries with high diversity. After the 4-component coupling, oxidation of the thioether to sulfone is followed by displacement of the latter by various carbon-centered nucleophiles (cyanide, malonate, boronic acids) or amines. The efficiency of the whole sequence was further demonstrated with one-pot procedures.
