Check Digit Verification of cas no

The CAS Registry Mumber 188650-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,5 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188650-93:
(8*1)+(7*8)+(6*8)+(5*6)+(4*5)+(3*0)+(2*9)+(1*3)=183
183 % 10 = 3
So 188650-93-3 is a valid CAS Registry Number.

Asymmetric synthesis of ibuprofen via diastereoselective alkylation of a homochiral N-acylbornanesultam

Oppolzer, Wolfgang,Rosset, Stephane,De Brabander, Jef

, p. 1539 - 1540 (1997)

A very short, 4 step synthesis of 2-(4-isobutylphenyl)propionic acid (ibuprofen) was achieved in 57% overall. yield, using a highly diastereoselective alkylation of the chiral enolate derived from N-(4-isobutylphenyl)acetyl bornanesultam as a key step.
