90822-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90822-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90822-44:
(7*9)+(6*0)+(5*8)+(4*2)+(3*2)+(2*4)+(1*4)=129
129 % 10 = 9
So 90822-44-9 is a valid CAS Registry Number.

Synthetic and conformational studies on anatoxin-a: A potent acetylcholine agonist
Koskinen,Rapoport
, p. 1301 - 1309 (2007/10/02)
Anatoxin-a is a powerful nicotinic acetylcholine receptor agonist. Its recently reported synthesis has been further optimized to provide anatoxin-a of >99% optical purity in 10% overall yield. The geometry of solid anatoxin-a has been determined by X-ray
