1204686-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1204686-04-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,6,8 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1204686-04:
(9*1)+(8*2)+(7*0)+(6*4)+(5*6)+(4*8)+(3*6)+(2*0)+(1*4)=133
133 % 10 = 3
So 1204686-04-3 is a valid CAS Registry Number.
