Check Digit Verification of cas no

The CAS Registry Mumber 500318-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,3,1 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 500318-50:
(8*5)+(7*0)+(6*0)+(5*3)+(4*1)+(3*8)+(2*5)+(1*0)=93
93 % 10 = 3
So 500318-50-3 is a valid CAS Registry Number.

Studies directed toward the total synthesis of pinnatoxin A: Synthesis of the 6,5,6-dispiroketal (BCD ring) system by double hemiketal formation/hetero-Michael addition strategy

Nakamura, Seiichi,Inagaki, Jun,Kudo, Masashi,Sugimoto, Tomohiro,Obara, Kohei,Nakajima, Makoto,Hashimoto, Shunichi

, p. 10353 - 10374 (2007/10/03)

An efficient, highly stereoselective synthesis of the C10-C26 portion of pinnatoxin A has been achieved, wherein the key step is a highly stereoselective construction of the 6,5,6-dispiroketal (BCD ring) system by an intramolecular hetero-Michael addition of a hemiketal alkoxide reversibly formed under the influence of lithium methoxide.
