Check Digit Verification of cas no

The CAS Registry Mumber 904684-90-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,8 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 904684-90:
(8*9)+(7*0)+(6*4)+(5*6)+(4*8)+(3*4)+(2*9)+(1*0)=188
188 % 10 = 8
So 904684-90-8 is a valid CAS Registry Number.

Metabolism of kalopanaxsaponin K by human intestinal bacteria and antirheumatoid arthritis activity of their metabolites.

Kim, Dong-Hyun,Bae, Eun-Ah,Han, Myung Joo,Park, Hee-Juhn,Choi, Jong-Won

, p. 68 - 71 (2002)

When kalopanaxsaponin K (KPK) from Kalopanax pictus was incubated for 24 h at 37 degrees C with human intestinal microflora, KPK was mainly metabolized to kalopanaxsaponin I (KPI) via kalopanaxsaponin H (KPH) rather than via kalopanaxsaponin J (KPJ), and then transformed to kalopanaxsaponin A (KPA) and hederagenin. Bacteroides sp., and Bifidobacterium sp. and Fusobacterium sp. transformed KPK to KPI and KPA and hederagenin via KPH or KPJ. However, Lactobacillus sp. and Streptococcus sp. transformed KPK to KPI, KPA, and hederagenin only via KPJ. The metabolite KPA of KPK showed potent antirheumatoid arthritis activity.
