351-92-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 351-92-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,5 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 351-92:
(5*3)+(4*5)+(3*1)+(2*9)+(1*2)=58
58 % 10 = 8
So 351-92-8 is a valid CAS Registry Number.

Syntheses of isocyanates via amines and carbonyl fluoride

Quan, Hengdao,Zhang, Ni,Zhou, Xiaomeng,Qian, Hua,Sekiya, Akira

, p. 26 - 30 (2015)

Isocyanates are widely used in many different areas, but the most common synthesis route-phosgene route cannot fit the more and more rigorous restriction of safety and environment. Here, a facile synthesis method of isocyanates via amines and carbonyl fluoride is proven feasibly by expanding its applications to the syntheses of nine different isocyanates. And two differences with the phosgene route are proposed. The reaction could occur under milder conditions and afford isocyanates in good yields, especially for the isocyanates containing electron withdrawing groups. It is appealing for industrial application.
