Check Digit Verification of cas no
The CAS Registry Mumber 38926-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,2 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 38926-45:
(7*3)+(6*8)+(5*9)+(4*2)+(3*6)+(2*4)+(1*5)=153
153 % 10 = 3
So 38926-45-3 is a valid CAS Registry Number.
