86209-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86209-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86209-90:
(7*8)+(6*6)+(5*2)+(4*0)+(3*9)+(2*9)+(1*0)=147
147 % 10 = 7
So 86209-90-7 is a valid CAS Registry Number.
