154051-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154051-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,0,5 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 154051-91:
(8*1)+(7*5)+(6*4)+(5*0)+(4*5)+(3*1)+(2*9)+(1*1)=109
109 % 10 = 9
So 154051-91-9 is a valid CAS Registry Number.
