Check Digit Verification of cas no
The CAS Registry Mumber 22899-62-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,8,9 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22899-62:
(7*2)+(6*2)+(5*8)+(4*9)+(3*9)+(2*6)+(1*2)=143
143 % 10 = 3
So 22899-62-3 is a valid CAS Registry Number.
