Check Digit Verification of cas no
The CAS Registry Mumber 200573-33-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 200573-33:
(8*2)+(7*0)+(6*0)+(5*5)+(4*7)+(3*3)+(2*3)+(1*3)=87
87 % 10 = 7
So 200573-33-7 is a valid CAS Registry Number.
