83206-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83206-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,0 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83206-11:
(7*8)+(6*3)+(5*2)+(4*0)+(3*6)+(2*1)+(1*1)=105
105 % 10 = 5
So 83206-11-5 is a valid CAS Registry Number.
