82604-30-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82604-30-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,6,0 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.Calculate Digit Verification of CAS Registry Number 82604-30:
(7*8)+(6*2)+(5*6)+(4*0)+(3*4)+(2*3)+(1*0)=116
116 % 10 = 6
So 82604-30-6 is a valid CAS Registry Number.
