109151-01-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109151-01-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,5 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109151-01:
(8*1)+(7*0)+(6*9)+(5*1)+(4*5)+(3*1)+(2*0)+(1*1)=91
91 % 10 = 1
So 109151-01-1 is a valid CAS Registry Number.
