Check Digit Verification of cas no
The CAS Registry Mumber 66165-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,6 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66165-37:
(7*6)+(6*6)+(5*1)+(4*6)+(3*5)+(2*3)+(1*7)=135
135 % 10 = 5
So 66165-37-5 is a valid CAS Registry Number.
