Check Digit Verification of cas no
The CAS Registry Mumber 213475-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,4,7 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 213475-01:
(8*2)+(7*1)+(6*3)+(5*4)+(4*7)+(3*5)+(2*0)+(1*1)=105
105 % 10 = 5
So 213475-01-5 is a valid CAS Registry Number.
