91774-25-3 Usage
Chemical Properties
White Crystalline Powder
Uses
Reacts specifically and rapidly with thiols to form mixed disulfides. [2-(Trimethylammonium)ethyl]methanethiosulfonate bromide is used to probe the structures of the ACh receptor channel of the GABAA receptor channel and of lactose permease.
Check Digit Verification of cas no
The CAS Registry Mumber 91774-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,7 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91774-25:
(7*9)+(6*1)+(5*7)+(4*7)+(3*4)+(2*2)+(1*5)=153
153 % 10 = 3
So 91774-25-3 is a valid CAS Registry Number.
