Check Digit Verification of cas no

The CAS Registry Mumber 1258791-29-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,7,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1258791-29:
(9*1)+(8*2)+(7*5)+(6*8)+(5*7)+(4*9)+(3*1)+(2*2)+(1*9)=195
195 % 10 = 5
So 1258791-29-5 is a valid CAS Registry Number.

Solid-phase synthesis of disubstituted N -acylureas from resin-bound ureas and acyl chlorides

Haecker, Hans-Georg,Meusel, Manuela,Aschfalk, Melanie,Guetschow, Michael

experimental part, p. 59 - 64 (2011/04/15)

Acylureas (ureides) are valued for their important biological activities. Whereas cyclic acylureas have frequently been the object of solid-phase chemistry, only few reports have focused on the solid-supported preparation of acyclic representatives. We have prepared different types of acylureas on Rink amide resin in three or four steps. The products are either N-acylated (9, 18), N-acylated-N′-alkylated (10, 19), or N-acylated-N-alkylated (22). Characteristic NMR parameters of isomeric acylureas 10, 19, and 22 are discussed.
