121610-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121610-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,1 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121610-69:
(8*1)+(7*2)+(6*1)+(5*6)+(4*1)+(3*0)+(2*6)+(1*9)=83
83 % 10 = 3
So 121610-69-3 is a valid CAS Registry Number.
