Check Digit Verification of cas no
The CAS Registry Mumber 223569-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,6 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 223569-31:
(8*2)+(7*2)+(6*3)+(5*5)+(4*6)+(3*9)+(2*3)+(1*1)=131
131 % 10 = 1
So 223569-31-1 is a valid CAS Registry Number.
