182572-04-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182572-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,5,7 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 182572-04:
(8*1)+(7*8)+(6*2)+(5*5)+(4*7)+(3*2)+(2*0)+(1*4)=139
139 % 10 = 9
So 182572-04-9 is a valid CAS Registry Number.
