138355-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138355-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,5 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138355-97:
(8*1)+(7*3)+(6*8)+(5*3)+(4*5)+(3*5)+(2*9)+(1*7)=152
152 % 10 = 2
So 138355-97-2 is a valid CAS Registry Number.

Anti-AIDS agents. Part 61: Anti-HIV activity of new podophyllotoxin derivatives
Zhu, Xiao-Kang,Guan, Jian,Xiao, Zhiyan,Cosentino, L. Mark,Lee, Kuo-Hsiung
, p. 4267 - 4273 (2007/10/03)
A series of novel podophyllotoxin derivatives containing structural modifications at C-4 (7-14), C-4′ (16-17), and the methylenedioxy A-ring (23-28) was synthesized and tested for inhibition of HIV replication. Four of these compounds (25-28) were previou
