Check Digit Verification of cas no

The CAS Registry Mumber 139461-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,6 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139461-38:
(8*1)+(7*3)+(6*9)+(5*4)+(4*6)+(3*1)+(2*3)+(1*8)=144
144 % 10 = 4
So 139461-38-4 is a valid CAS Registry Number.

Straightforward Approach Toward Dihydrothiazoles via Intramolecular Bromocyclization

Sadat-Ebrahimi, Seyed Esmail,Ganjizadeh Zarj, Marzieh,Moghimi, Setareh,Yahya-Meymandi, Azadeh,Mahdavi, Mohammad,Arab, Saman,Shafiee, Abbas,Foroumadi, Alireza

, p. 2142 - 2147 (2015/09/01)

An intramolecular bromonium ion-assisted cyclization with sulfur as an internal nucleophile is described. Starting from benzoyl chlorides, this method provides an easy procedure for the synthesis of dihydrothiazole derivatives in moderate to good yields.

A convenient and efficient method for the synthesis of mono- and N,N-disubstituted thioureas

Kodomari, Mitsuo,Suzuki, Masato,Tanigawa, Keiko,Aoyama, Tadashi

, p. 5841 - 5843 (2007/10/03)

A convenient method for the synthesis of mono- and N,N-disubstituted thioureas by the debenzoylation of N-substituted- and N,N-disubstituted- N′-benzoylthioureas with hydrazine hydrate under solvent-free conditions has been developed. N-Substituted-N′-benzoylthioureas and hydrazine hydrate were mixed, and stirred at room temperature without a solvent to give the corresponding N-substituted thioureas in high yields.
