Check Digit Verification of cas no
The CAS Registry Mumber 121659-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121659-64:
(8*1)+(7*2)+(6*1)+(5*6)+(4*5)+(3*9)+(2*6)+(1*4)=121
121 % 10 = 1
So 121659-64-1 is a valid CAS Registry Number.
