Check Digit Verification of cas no

The CAS Registry Mumber 180629-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,2 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180629-42:
(8*1)+(7*8)+(6*0)+(5*6)+(4*2)+(3*9)+(2*4)+(1*2)=139
139 % 10 = 9
So 180629-42-9 is a valid CAS Registry Number.

Studies on the reactivity of cephalosporins. 6. Ozonolysis of Δ2-cephem derivatives as a new entry to highly functionalized 2-oxoazetidine and 2-oxoazetidine-4-sulfenic acid derivatives

Botta, Maurizio,Crocianelli, Marcello,Saladino, Raffaele,Mozzetti, Cristina,Nicoletti, Rosario

, p. 10205 - 10214 (1996)

The ozonolysis of Δ2-cephem derivatives 1, 2, and 3, to obtain highly functionalized 2-oxoazetidine and 2-oxoazetidine-4-sulfenic acid derivatives is described. An efficient and selective synthesis of the oxapenem derivative 16 is also reported
