Check Digit Verification of cas no

The CAS Registry Mumber 135121-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,2 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135121-20:
(8*1)+(7*3)+(6*5)+(5*1)+(4*2)+(3*1)+(2*2)+(1*0)=79
79 % 10 = 9
So 135121-20-9 is a valid CAS Registry Number.

Synthesis, Binding Properties and Self-functionalization of a Steroid-capped Porphyrin

Bonar-Law, Richard P.,Sanders, Jeremy K. M.

, p. 574 - 577 (1991)

A porphyrin capped with a steroidal superstructure bearing convergent hydroxy groups has been synthesized and shown to bind a variety of functionalized amines via a combination of metal-amine and hydrogen-bonding interactions; the metal-ligand interaction was used to catalyse and control selective acylation of a single hydroxy group in the cap.
