Check Digit Verification of cas no

The CAS Registry Mumber 128291-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128291-13:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*1)+(2*1)+(1*3)=124
124 % 10 = 4
So 128291-13-4 is a valid CAS Registry Number.

Electroreductive cyclization reactions. Stereoselection, creation of quaternary centers in bicyclic frameworks, and a formal total synthesis of quadrone

Sowell, C. Gregory,Wolin, Ronald L.,Little, R. Daniel

, p. 485 - 488 (2007/10/02)

The electroreductive cyclization reaction has been successfully applied to an efficient formal total synthesis of quadrone (1). Two of the four rings were created electrochemically, a third via a novel oxidativedecarboxylation and cyclization onto a remote nitrile functional group (22a24).
