Check Digit Verification of cas no
The CAS Registry Mumber 27908-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,9,0 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27908-75:
(7*2)+(6*7)+(5*9)+(4*0)+(3*8)+(2*7)+(1*5)=144
144 % 10 = 4
So 27908-75-4 is a valid CAS Registry Number.
