Check Digit Verification of cas no
The CAS Registry Mumber 16223-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16223-99:
(7*1)+(6*6)+(5*2)+(4*2)+(3*3)+(2*9)+(1*9)=97
97 % 10 = 7
So 16223-99-7 is a valid CAS Registry Number.
