124267-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124267-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,6 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 124267-32:
(8*1)+(7*2)+(6*4)+(5*2)+(4*6)+(3*7)+(2*3)+(1*2)=109
109 % 10 = 9
So 124267-32-9 is a valid CAS Registry Number.
