118458-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118458-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,5 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118458-72:
(8*1)+(7*1)+(6*8)+(5*4)+(4*5)+(3*8)+(2*7)+(1*2)=143
143 % 10 = 3
So 118458-72-3 is a valid CAS Registry Number.
