Check Digit Verification of cas no
The CAS Registry Mumber 19990-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19990-01:
(7*1)+(6*9)+(5*9)+(4*9)+(3*0)+(2*0)+(1*1)=143
143 % 10 = 3
So 19990-01-3 is a valid CAS Registry Number.
