Check Digit Verification of cas no
The CAS Registry Mumber 50634-01-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,3 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 50634-01:
(7*5)+(6*0)+(5*6)+(4*3)+(3*4)+(2*0)+(1*1)=90
90 % 10 = 0
So 50634-01-0 is a valid CAS Registry Number.
