121004-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121004-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,0 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121004-17:
(8*1)+(7*2)+(6*1)+(5*0)+(4*0)+(3*4)+(2*1)+(1*7)=49
49 % 10 = 9
So 121004-17-9 is a valid CAS Registry Number.
