1126639-55-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1126639-55-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,6,3 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1126639-55:
(9*1)+(8*1)+(7*2)+(6*6)+(5*6)+(4*3)+(3*9)+(2*5)+(1*5)=151
151 % 10 = 1
So 1126639-55-1 is a valid CAS Registry Number.
