908040-07-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 908040-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,8,0,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 908040-07:
(8*9)+(7*0)+(6*8)+(5*0)+(4*4)+(3*0)+(2*0)+(1*7)=143
143 % 10 = 3
So 908040-07-3 is a valid CAS Registry Number.

Synthesis of α-aliphatic and β-aromatic substituted taurines via regioselective ring opening of thiiranes with ammonia

Yu, Hao,Cao, Shengli,Zhang, Leilei,Liu, Gang,Xu, Jiaxi

, p. 2205 - 2209 (2009)

Thiiranes are important starting materials for the synthesis of substituted taurines. The regioselectivity of ring-opening reactions of thiiranes with ammonia in the presence of silver nitrate was investigated. The results of the ring-opening reaction and subsequent peroxy acid oxidation indicate that alkyl-substituted thiiranes give rise to 1-monoalkyl- and 1,1-dialkyltaurines, whereas aryl-substituted thiiranes produce 2-aryl-, 2-alkyl-2-aryl-, and 2,2-diaryltaurines. This shows that alkyl-substituted thiiranes were attacked on their less-substituted ring carbon atoms, while aryl-substituted thiiranes were attacked on their more substituted ring carbon atoms. The current method is an effective and atom-economic route for the synthesis of mono- and disubstituted α-alkyl-and β-aryl-substituted taurines. Georg Thieme Verlag Stuttgart.
