Check Digit Verification of cas no

The CAS Registry Mumber 4340-26-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,4 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4340-26:
(6*4)+(5*3)+(4*4)+(3*0)+(2*2)+(1*6)=65
65 % 10 = 5
So 4340-26-5 is a valid CAS Registry Number.

N- AND O-CARBAMOYL AND THIOCARBAMOYL DERIVATIVES OF &β-LACTAM ANTIBIOTICS

Petrulyanis, L. N.,Veinberg, G. A.,Kononov, L. I.,Dreibante, I. I.,Lukevits, E. Ya.

, p. 279 - 282 (1985)

New N-acylureido and N-acylthioureido derivatives of β-lactam antibiotics were obtained by the reaction of 6-ureido and 6-thioureidopenicillanic and 7-thioreidodeacetoxycephalosporanic acids with acyl halides of carboxylic acids and benzoyl isocyanate. 6-Carbamoylhydroxypenicillanic acid, 6-thiocarbamoylhydroxypenicillanic acid, and its trichloroethyl ester were obtained by treatment of 6-α-hydroxypenicillanic acid and its trichloroethyl ester with isocyanatosilanes with subsequent hydrolysis of the N-silylcyanato groups.
