21168-36-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21168-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21168-36:
(7*2)+(6*1)+(5*1)+(4*6)+(3*8)+(2*3)+(1*6)=85
85 % 10 = 5
So 21168-36-5 is a valid CAS Registry Number.
