156317-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156317-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,1 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156317-47:
(8*1)+(7*5)+(6*6)+(5*3)+(4*1)+(3*7)+(2*4)+(1*7)=134
134 % 10 = 4
So 156317-47-4 is a valid CAS Registry Number.

Tandem enzymatic oxygenations in biosynthesis of epoxyquinone pharmacophore of manumycin-type metabolites
Rui, Zhe,Sandy, Moriah,Jung, Brian,Zhang, Wenjun
, p. 879 - 887 (2013/08/23)
Many natural products contain epoxyquinone pharmacophore with unknown biosynthetic mechanisms. Recent genetic analysis of the asukamycin biosynthetic gene cluster proposed enzyme candidates related to epoxyquinone formation for manumycin-type metabolites.
