1280686-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1280686-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,6,8 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1280686-02:
(9*1)+(8*2)+(7*8)+(6*0)+(5*6)+(4*8)+(3*6)+(2*0)+(1*2)=163
163 % 10 = 3
So 1280686-02-3 is a valid CAS Registry Number.
