125659-84-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125659-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,5 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 125659-84:
(8*1)+(7*2)+(6*5)+(5*6)+(4*5)+(3*9)+(2*8)+(1*4)=149
149 % 10 = 9
So 125659-84-9 is a valid CAS Registry Number.
