58133-67-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58133-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,1,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 58133-67:
(7*5)+(6*8)+(5*1)+(4*3)+(3*3)+(2*6)+(1*7)=128
128 % 10 = 8
So 58133-67-8 is a valid CAS Registry Number.
