Check Digit Verification of cas no
The CAS Registry Mumber 13657-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13657-90:
(7*1)+(6*3)+(5*6)+(4*5)+(3*7)+(2*9)+(1*0)=114
114 % 10 = 4
So 13657-90-4 is a valid CAS Registry Number.
