147124-31-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147124-31-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,2 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 147124-31:
(8*1)+(7*4)+(6*7)+(5*1)+(4*2)+(3*4)+(2*3)+(1*1)=110
110 % 10 = 0
So 147124-31-0 is a valid CAS Registry Number.
