Check Digit Verification of cas no

The CAS Registry Mumber 922716-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,2,7,1 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 922716-09:
(8*9)+(7*2)+(6*2)+(5*7)+(4*1)+(3*6)+(2*0)+(1*9)=164
164 % 10 = 4
So 922716-09-4 is a valid CAS Registry Number.

Syntheses and antibacterial activities of diterpene catechol derivatives with abietane, totarane and podocarpane skeletons against methicillin-resistant Staphylococcus aureus and Propionibacterium acnes

Tada, Masahiro,Kurabe, Jun,Yoshida, Takashi,Ohkanda, Tomoyuki,Matsumoto, Yusuke

, p. 818 - 824 (2010)

Natural catechol, quinone and quinone methide diterpenes with abietane (15-deoxyfuerstione, taxodione) and totarane (dispermone, 12,13-dihydroxy-8,11, 13-totaratriene-6-one), and podocarpane (nimbidiol, deoxynimbidiol) skeletons were synthesized using ortho-oxidation of phenol with meta-chlorobenzoyl peroxide. Minimum inhibitory activities of these diterpenes and previously synthesized natural diterpenes were measured against methicillin-resistant Staphylococcus aureus (MRSA) and Propionibacterium acnes, which cause serious skin infection associated with acne. Abietaquinone methide and 8,11,13-totaratriene-12,13-diol showed potent activities against S. aureus (MRSA) and P. acnes, and no serious toxicity by oral dose to mice.
