Check Digit Verification of cas no
The CAS Registry Mumber 19019-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,1 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19019-33:
(7*1)+(6*9)+(5*0)+(4*1)+(3*9)+(2*3)+(1*3)=101
101 % 10 = 1
So 19019-33-1 is a valid CAS Registry Number.
