Check Digit Verification of cas no
The CAS Registry Mumber 54397-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54397-98:
(7*5)+(6*4)+(5*3)+(4*9)+(3*7)+(2*9)+(1*8)=157
157 % 10 = 7
So 54397-98-7 is a valid CAS Registry Number.
