Check Digit Verification of cas no
The CAS Registry Mumber 121562-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,6 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121562-09:
(8*1)+(7*2)+(6*1)+(5*5)+(4*6)+(3*2)+(2*0)+(1*9)=92
92 % 10 = 2
So 121562-09-2 is a valid CAS Registry Number.
