Check Digit Verification of cas no
The CAS Registry Mumber 121961-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,6 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121961-20:
(8*1)+(7*2)+(6*1)+(5*9)+(4*6)+(3*1)+(2*2)+(1*0)=104
104 % 10 = 4
So 121961-20-4 is a valid CAS Registry Number.
