124740-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124740-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,4 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124740-06:
(8*1)+(7*2)+(6*4)+(5*7)+(4*4)+(3*0)+(2*0)+(1*6)=103
103 % 10 = 3
So 124740-06-3 is a valid CAS Registry Number.
