Check Digit Verification of cas no

The CAS Registry Mumber 863604-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,6,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 863604-34:
(8*8)+(7*6)+(6*3)+(5*6)+(4*0)+(3*4)+(2*3)+(1*4)=176
176 % 10 = 6
So 863604-34-6 is a valid CAS Registry Number.

Total synthesis of asimicin via highly stereoselective [3 + 2] annulation reactions of substituted allylsilanes

Tinsley, Jennifer M.,Roush, William R.

, p. 10818 - 10819 (2007/10/03)

A highly stereoselective total synthesis of (+)-asimicin (1) is reported. The synthesis features two chelate-controlled [3 + 2] annulation reactions - one of which (e.g., 2 + 3) constitutes a key, convergent fragment assembly step - that establish all of the stereochemistry of the bis-tetrahydrofuran unit of the natural product.
