124097-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124097-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,9 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 124097-64:
(8*1)+(7*2)+(6*4)+(5*0)+(4*9)+(3*7)+(2*6)+(1*4)=119
119 % 10 = 9
So 124097-64-9 is a valid CAS Registry Number.
