134984-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134984-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,8 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134984-99:
(8*1)+(7*3)+(6*4)+(5*9)+(4*8)+(3*4)+(2*9)+(1*9)=169
169 % 10 = 9
So 134984-99-9 is a valid CAS Registry Number.

, p. 11633 - 11644 (2007/10/03)
A viable synthetic route to the furaquinocin-class antibiotics is described. The key steps include (1) Co-complex mediated stereospecific 1,2- shift of an alkynyl group (9 → 6) to establish the c(2)-C(3) stereochemical relationship, (2) efficient construc
