862206-07-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862206-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,2,0 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 862206-07:
(8*8)+(7*6)+(6*2)+(5*2)+(4*0)+(3*6)+(2*0)+(1*7)=153
153 % 10 = 3
So 862206-07-3 is a valid CAS Registry Number.
