Check Digit Verification of cas no
The CAS Registry Mumber 213615-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,1 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213615-55:
(8*2)+(7*1)+(6*3)+(5*6)+(4*1)+(3*5)+(2*5)+(1*5)=105
105 % 10 = 5
So 213615-55-5 is a valid CAS Registry Number.
