Check Digit Verification of cas no

The CAS Registry Mumber 30755-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,7,5 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30755-74:
(7*3)+(6*0)+(5*7)+(4*5)+(3*5)+(2*7)+(1*4)=109
109 % 10 = 9
So 30755-74-9 is a valid CAS Registry Number.

Visible-light photocatalyzed oxidative decarboxylation of oxamic acids: a green route to urethanes and ureas

Pawar, Govind Goroba,Robert, Frédéric,Grau, Etienne,Cramail, Henri,Landais, Yannick

supporting information, p. 9337 - 9340 (2018/08/31)

A sustainable metal-free route to urethanes and ureas based on a photocatalyzed oxidative decarboxylation of oxamic acids is described. The reaction includes in situ generation of an isocyanate from the oxamic acid, using an organic dye as a photocatalyst, a hypervalent iodine reagent as an oxidant and a light source, which trigger the free-radical decarboxylation. This protocol successfully avoids the isolation, purification and storage of carcinogenic isocyanates and allows elaboration of urethanes and ureas in a one-pot process from commercially available sources.
