124569-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124569-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,6 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124569-68:
(8*1)+(7*2)+(6*4)+(5*5)+(4*6)+(3*9)+(2*6)+(1*8)=142
142 % 10 = 2
So 124569-68-2 is a valid CAS Registry Number.
