213835-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213835-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,3 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213835-99:
(8*2)+(7*1)+(6*3)+(5*8)+(4*3)+(3*5)+(2*9)+(1*9)=135
135 % 10 = 5
So 213835-99-5 is a valid CAS Registry Number.
