Check Digit Verification of cas no

The CAS Registry Mumber 1255944-47-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,9,4 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1255944-47:
(9*1)+(8*2)+(7*5)+(6*5)+(5*9)+(4*4)+(3*4)+(2*4)+(1*7)=178
178 % 10 = 8
So 1255944-47-8 is a valid CAS Registry Number.

Combining designer cells and click chemistry for a one-pot four-step preparation of enantiopure β-hydroxytriazoles

Szymanski, Wiktor,Postema, Christiaan P.,Tarabiono, Chiara,Berthiol, Florian,Campbell-Verduyn, Lachlan,De Wildeman, Stefaan,De Vries, Johannes G.,Feringa, Ben L.,Janssen, Dick B.

, p. 2111 - 2115 (2010)

The multistep catalytic process using designer cells, either added as freshly prepared suspensions or as stable lyophilized powder, and click reaction can be performed in one pot. The sequence of four reactions allows the production of both enantiomers of β-hydroxytriazoles with high enantiomeric excess.
