686279-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 686279-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,6,2,7 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 686279-58:
(8*6)+(7*8)+(6*6)+(5*2)+(4*7)+(3*9)+(2*5)+(1*8)=223
223 % 10 = 3
So 686279-58-3 is a valid CAS Registry Number.
