109925-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109925-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,2 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109925-85:
(8*1)+(7*0)+(6*9)+(5*9)+(4*2)+(3*5)+(2*8)+(1*5)=151
151 % 10 = 1
So 109925-85-1 is a valid CAS Registry Number.
