Check Digit Verification of cas no

The CAS Registry Mumber 634616-18-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,6,1 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 634616-18:
(8*6)+(7*3)+(6*4)+(5*6)+(4*1)+(3*6)+(2*1)+(1*8)=155
155 % 10 = 5
So 634616-18-5 is a valid CAS Registry Number.

Ruthenium-Mediated Isomerization and Ring-Closing Metathesis: Versatile Syntheses of 6-, 7- and 8-Membered Benzo-Fused Heterocycles

Van Otterlo, Willem A. L.,Pathak, Rakhi,De Koning, Charles B.

, p. 1859 - 1861 (2007/10/03)

Ruthenium-mediated isomerization and ring-closing metathesis (RCM) were the key steps used to convert a simple substrate, 2-allyl-3-isopropoxy-4-methoxybenzaldehyde, into a variety of 6-, 7- and 8-membered nitrogen- and oxygen-containing benzofused hetero
