109072-52-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109072-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109072-52:
(8*1)+(7*0)+(6*9)+(5*0)+(4*7)+(3*2)+(2*5)+(1*2)=108
108 % 10 = 8
So 109072-52-8 is a valid CAS Registry Number.
