30018-41-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30018-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,0,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 30018-41:
(7*3)+(6*0)+(5*0)+(4*1)+(3*8)+(2*4)+(1*1)=58
58 % 10 = 8
So 30018-41-8 is a valid CAS Registry Number.
