239796-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 239796-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,9,7,9 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 239796-25:
(8*2)+(7*3)+(6*9)+(5*7)+(4*9)+(3*6)+(2*2)+(1*5)=189
189 % 10 = 9
So 239796-25-9 is a valid CAS Registry Number.
