Check Digit Verification of cas no
The CAS Registry Mumber 52256-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,5 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52256-37:
(7*5)+(6*2)+(5*2)+(4*5)+(3*6)+(2*3)+(1*7)=108
108 % 10 = 8
So 52256-37-8 is a valid CAS Registry Number.
