Check Digit Verification of cas no
The CAS Registry Mumber 19156-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,5 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19156-50:
(7*1)+(6*9)+(5*1)+(4*5)+(3*6)+(2*5)+(1*0)=114
114 % 10 = 4
So 19156-50-4 is a valid CAS Registry Number.
