123825-39-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123825-39-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,2 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123825-39:
(8*1)+(7*2)+(6*3)+(5*8)+(4*2)+(3*5)+(2*3)+(1*9)=118
118 % 10 = 8
So 123825-39-8 is a valid CAS Registry Number.
