121696-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121696-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,9 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121696-07:
(8*1)+(7*2)+(6*1)+(5*6)+(4*9)+(3*6)+(2*0)+(1*7)=119
119 % 10 = 9
So 121696-07-9 is a valid CAS Registry Number.
