87574-58-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87574-58-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,7 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87574-58:
(7*8)+(6*7)+(5*5)+(4*7)+(3*4)+(2*5)+(1*8)=181
181 % 10 = 1
So 87574-58-1 is a valid CAS Registry Number.
