1046451-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1046451-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,4,5 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1046451-53:
(9*1)+(8*0)+(7*4)+(6*6)+(5*4)+(4*5)+(3*1)+(2*5)+(1*3)=129
129 % 10 = 9
So 1046451-53-9 is a valid CAS Registry Number.
