1451070-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1451070-67-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,1,0,7 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1451070-67:
(9*1)+(8*4)+(7*5)+(6*1)+(5*0)+(4*7)+(3*0)+(2*6)+(1*7)=129
129 % 10 = 9
So 1451070-67-9 is a valid CAS Registry Number.
