Check Digit Verification of cas no
The CAS Registry Mumber 121794-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,9 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121794-97:
(8*1)+(7*2)+(6*1)+(5*7)+(4*9)+(3*4)+(2*9)+(1*7)=136
136 % 10 = 6
So 121794-97-6 is a valid CAS Registry Number.
