Check Digit Verification of cas no

The CAS Registry Mumber 1228243-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1228243-16:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*4)+(3*3)+(2*1)+(1*6)=130
130 % 10 = 0
So 1228243-16-0 is a valid CAS Registry Number.

Determination of the absolute configuration of nodulisporacid A by the concise synthesis of four stereoisomers via three-component reaction and one-pot construction of the framework

Sumiya, Tatsunobu,Ishigami, Ken,Watanabe, Hidenori

, p. 2765 - 2767 (2010)

Four stereoisomers of nodulisporacid A (1) were synthesized by the concise approach which includes three-component reaction and subsequent one-pot construction of the whole framework. The 1H NMR comparison of the derivatives (10-12) revealed the absolute configuration of natural 1 to be 4R,4′R,6′R.
