Check Digit Verification of cas no
The CAS Registry Mumber 500992-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,9,9 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 500992-22:
(8*5)+(7*0)+(6*0)+(5*9)+(4*9)+(3*2)+(2*2)+(1*2)=133
133 % 10 = 3
So 500992-22-3 is a valid CAS Registry Number.
