Check Digit Verification of cas no
The CAS Registry Mumber 20721-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,2 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20721-18:
(7*2)+(6*0)+(5*7)+(4*2)+(3*1)+(2*1)+(1*8)=70
70 % 10 = 0
So 20721-18-0 is a valid CAS Registry Number.

Emimycin and its nucleoside derivatives: Synthesis and antiviral activity

, p. 93 - 103 (2017/12/26)
The synthesis of emimycin, 5-substituted emimycin analogues and the corresponding ribo- and 2′-deoxyribonucleoside derivatives is described. Emimycin, its 5-substituted congeners and the ribonucleoside derivatives are completely devoid of antiviral activity against RNA viruses. In contrast, some of the 2′-deoxyribosyl emimycin derivatives are potent inhibitors of the replication of herpes simplex virus-1 and varicella-zoster virus, lacking cytotoxicity.
