Check Digit Verification of cas no
The CAS Registry Mumber 202338-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,3,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 202338-72:
(8*2)+(7*0)+(6*2)+(5*3)+(4*3)+(3*8)+(2*7)+(1*2)=95
95 % 10 = 5
So 202338-72-5 is a valid CAS Registry Number.
