Check Digit Verification of cas no
The CAS Registry Mumber 1583-58-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,8 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1583-58:
(6*1)+(5*5)+(4*8)+(3*3)+(2*5)+(1*8)=90
90 % 10 = 0
So 1583-58-0 is a valid CAS Registry Number.
