Check Digit Verification of cas no
The CAS Registry Mumber 119522-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,2 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119522-51:
(8*1)+(7*1)+(6*9)+(5*5)+(4*2)+(3*2)+(2*5)+(1*1)=119
119 % 10 = 9
So 119522-51-9 is a valid CAS Registry Number.
