180724-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180724-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,2 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 180724-47:
(8*1)+(7*8)+(6*0)+(5*7)+(4*2)+(3*4)+(2*4)+(1*7)=134
134 % 10 = 4
So 180724-47-4 is a valid CAS Registry Number.
