Check Digit Verification of cas no

The CAS Registry Mumber 1418283-94-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,8,2,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1418283-94:
(9*1)+(8*4)+(7*1)+(6*8)+(5*2)+(4*8)+(3*3)+(2*9)+(1*4)=169
169 % 10 = 9
So 1418283-94-9 is a valid CAS Registry Number.

Development of a concise synthesis of ouabagenin and hydroxylated corticosteroid analogues

Renata, Hans,Zhou, Qianghui,Dünstl, Georg,Felding, Jakob,Merchant, Rohan R.,Yeh, Chien-Hung,Baran, Phil S.

, p. 1330 - 1340 (2015)

The natural product ouabagenin is a complex cardiotonic steroid with a highly oxygenated skeleton. This full account describes the development of a concise synthesis of ouabagenin, including the evolution of synthetic strategy to access hydroxylation at the C19 position of a steroid skeleton. In addition, approaches to install the requisite butenolide moiety at the C17 position are discussed. Lastly, methodology developed in this synthesis has been applied in the generation of novel analogues of corticosteroid drugs bearing a hydroxyl group at the C19 position.(Chemical Equation Presented).
