4282-30-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4282-30-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4282-30:
(6*4)+(5*2)+(4*8)+(3*2)+(2*3)+(1*0)=78
78 % 10 = 8
So 4282-30-8 is a valid CAS Registry Number.
