Check Digit Verification of cas no

The CAS Registry Mumber 71155-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,5 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71155-08:
(7*7)+(6*1)+(5*1)+(4*5)+(3*5)+(2*0)+(1*8)=103
103 % 10 = 3
So 71155-08-3 is a valid CAS Registry Number.

An alternative synthesis of the Corey prostaglandin aldehyde.

Peel,Sutherland

, p. 151 - 153 (2007/10/11)

This is a detailed description of 1 route to the chemical synthesis of PGs (prostaglandins) and their analogs in the laboratory. The chemical formula and chemical structure of each step in the chain is diagrammed. The aldehyde had served as intermediary in the synthesizing process in previous experiments. In this series of steps, the starting stage was the Prins reaction of norbornadiene and paraform-aldehyde in formic acid. Lactones were used as starting materials in the synthesis. Hydrolysis and oxidation were used to change 1 substance in the process into the next.
