Check Digit Verification of cas no
The CAS Registry Mumber 95790-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,7,9 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 95790-69:
(7*9)+(6*5)+(5*7)+(4*9)+(3*0)+(2*6)+(1*9)=185
185 % 10 = 5
So 95790-69-5 is a valid CAS Registry Number.
