83027-10-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83027-10-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,2 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83027-10:
(7*8)+(6*3)+(5*0)+(4*2)+(3*7)+(2*1)+(1*0)=105
105 % 10 = 5
So 83027-10-5 is a valid CAS Registry Number.
