132746-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132746-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,4 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 132746-03:
(8*1)+(7*3)+(6*2)+(5*7)+(4*4)+(3*6)+(2*0)+(1*3)=113
113 % 10 = 3
So 132746-03-3 is a valid CAS Registry Number.

, p. 2271 - 2276 (1991)
The absolute stereochemistry of hancokinol, hancolupenone, hancolupenol, hancolupenol hexacosanoate, which are novel triterpenes, from Cynanchum hancokianum, has been elucidated by means of spectroscopic [nuclear magnetic resonance (NMR), circular dichroism (CD)] analyses.
