Check Digit Verification of cas no

The CAS Registry Mumber 1450892-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,8,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1450892-20:
(9*1)+(8*4)+(7*5)+(6*0)+(5*8)+(4*9)+(3*2)+(2*2)+(1*0)=162
162 % 10 = 2
So 1450892-20-2 is a valid CAS Registry Number.

Silver carboxylate promoted lactonization: A general method applicable to prepare medium and large-sized lactones without high dilution or slow addition

Liu, Le,Xu, Shimin,Zhou, Hongwei

, p. 8386 - 8391 (2013)

Efficient and applicable approach to macrolactonizations, with ready availability of starting materials and simple operation, remains a challenging task for the organic community. We developed a 'freshman-can-do' protocol to medium- and large-sized lactones, not depending on high-dilution or slow addition techniques. Application of this method for the synthesis of natural lactones or potentially pharmaceutical compounds might be useful for organic chemists and pharmacists.
