Check Digit Verification of cas no

The CAS Registry Mumber 1280551-80-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,5,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1280551-80:
(9*1)+(8*2)+(7*8)+(6*0)+(5*5)+(4*5)+(3*1)+(2*8)+(1*0)=145
145 % 10 = 5
So 1280551-80-5 is a valid CAS Registry Number.

Highly efficient total synthesis of the clostridium-derived anti-MRSA antibiotic closthioamide

Kloss, Florian,Lincke, Thorger,Hertweck, Christian

, p. 1429 - 1431 (2011)

The antibiotic closthioamide from Clostridium cellulolyticum, the first example of a secondary metabolite from strictly anaerobic bacteria, was synthesized by a versatile and highly efficient synthetic route. This starts from simple building blocks and involves convergent peptide coupling and polythionation.
