83206-05-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83206-05-7 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, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83206-05:
(7*8)+(6*3)+(5*2)+(4*0)+(3*6)+(2*0)+(1*5)=107
107 % 10 = 7
So 83206-05-7 is a valid CAS Registry Number.
