842141-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 842141-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,2,1,4 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 842141-70:
(8*8)+(7*4)+(6*2)+(5*1)+(4*4)+(3*1)+(2*7)+(1*0)=142
142 % 10 = 2
So 842141-70-2 is a valid CAS Registry Number.

Studies toward the total synthesis of sorangicins: Asymmetric synthesis of the key fragments
Schinzer, Dieter,Schulz, Claudia,Krug, Olga
, p. 2689 - 2692 (2004)
Efficient synthesis of the key fragments of the complex antibiotics class of sorangicins (Scheme 1) is described. Starting from simple compounds fragments I, II, and IV can be synthesized. For fragment III we chose an approach via L-glucal.
