172900-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172900-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172900-99:
(8*1)+(7*7)+(6*2)+(5*9)+(4*0)+(3*0)+(2*9)+(1*9)=141
141 % 10 = 1
So 172900-99-1 is a valid CAS Registry Number.

Dong, Hua,Zhang, Zhi-Liu,Huang, Jia-Hui,Ma, Rujian,Chen, Shu-Hui,Li, Ge
, p. 6337 - 6340 (2007/10/03)
A convergent synthesis of aliskiren was accomplished via the use of Segment AB as the key intermediate, which was prepared via the coupling of the Grignard reagent derived from Segment B with Segment A, followed by subsequent oxidative lactonization.
