Check Digit Verification of cas no
The CAS Registry Mumber 213819-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213819-49:
(8*2)+(7*1)+(6*3)+(5*8)+(4*1)+(3*9)+(2*4)+(1*9)=129
129 % 10 = 9
So 213819-49-9 is a valid CAS Registry Number.
