4526-18-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4526-18-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.Calculate Digit Verification of CAS Registry Number 4526-18:
(6*4)+(5*5)+(4*2)+(3*6)+(2*1)+(1*8)=85
85 % 10 = 5
So 4526-18-5 is a valid CAS Registry Number.
