1400472-52-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1400472-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,4,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1400472-52:
(9*1)+(8*4)+(7*0)+(6*0)+(5*4)+(4*7)+(3*2)+(2*5)+(1*2)=107
107 % 10 = 7
So 1400472-52-7 is a valid CAS Registry Number.
