121230-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121230-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,3 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121230-91:
(8*1)+(7*2)+(6*1)+(5*2)+(4*3)+(3*0)+(2*9)+(1*1)=69
69 % 10 = 9
So 121230-91-9 is a valid CAS Registry Number.
