21879-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21879-81-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,7 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21879-81:
(7*2)+(6*1)+(5*8)+(4*7)+(3*9)+(2*8)+(1*1)=132
132 % 10 = 2
So 21879-81-2 is a valid CAS Registry Number.
