Check Digit Verification of cas no
The CAS Registry Mumber 500997-67-1 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 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 500997-67:
(8*5)+(7*0)+(6*0)+(5*9)+(4*9)+(3*7)+(2*6)+(1*7)=161
161 % 10 = 1
So 500997-67-1 is a valid CAS Registry Number.
