Check Digit Verification of cas no
The CAS Registry Mumber 5633-18-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,3 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5633-18:
(6*5)+(5*6)+(4*3)+(3*3)+(2*1)+(1*8)=91
91 % 10 = 1
So 5633-18-1 is a valid CAS Registry Number.
