Check Digit Verification of cas no
The CAS Registry Mumber 121003-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,0 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121003-24:
(8*1)+(7*2)+(6*1)+(5*0)+(4*0)+(3*3)+(2*2)+(1*4)=45
45 % 10 = 5
So 121003-24-5 is a valid CAS Registry Number.

Photochemical reactions of acyclic and semicyclic monothioimides were studied.Photolysis of acyclic monothioimides gave β-lactams (Type II cyclization products) and thioamides (Type II cleavage products). 4-Mercapto-β-lactams were isolated as 4-acylthio-β-lactams by acylation with benzoyl chloride or acetyl chloride in the presence of triethylamine.Irradation of six- or seven- membered semicyclic monothioimides gave bicyclic β-lactams, but five-membered semicyclic monothioimides gave only Type II cleavage products.
