810667-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 810667-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,0,6,6 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 810667-58:
(8*8)+(7*1)+(6*0)+(5*6)+(4*6)+(3*7)+(2*5)+(1*8)=164
164 % 10 = 4
So 810667-58-4 is a valid CAS Registry Number.
