Check Digit Verification of cas no

The CAS Registry Mumber 497063-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,0,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 497063-20:
(8*4)+(7*9)+(6*7)+(5*0)+(4*6)+(3*3)+(2*2)+(1*0)=174
174 % 10 = 4
So 497063-20-4 is a valid CAS Registry Number.

Synthesis of 3-oxooxa- and 3-oxoazacycloalk-4-enes by ring-closing metathesis. Application to the synthesis of an inhibitor of cathepsin K

Taillier, Catherine,Hameury, Thomas,Bellosta, Véronique,Cossy, Janine

, p. 4472 - 4490 (2008/02/01)

3-Oxooxa- and 3-oxoazacycloalk-4-enes were obtained with good yield from 1-(ω-alkenyloxy)- and 1-(ω-alkenylamino)-but-3-en-2-ones by using a ring-closing metathesis. This methodology has been used to synthesize an inhibitor of cathepsin K.
