1187038-43-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187038-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,0,3 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1187038-43:
(9*1)+(8*1)+(7*8)+(6*7)+(5*0)+(4*3)+(3*8)+(2*4)+(1*3)=162
162 % 10 = 2
So 1187038-43-2 is a valid CAS Registry Number.

De novo synthesis of modified saxitoxins for sodium ion channel study
Andresen, Brian M.,Du Bois
supporting information; experimental part, p. 12524 - 12525 (2010/01/29)
(Chemical Equation Presented) Access to novel forms of (+)-saxitoxin (STX), a potent and selective inhibitor of voltage-gated Na+ ion channels, has been made possible through de novo synthesis. Saxitoxin is believed to lodge in the outer mouth
