84211-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84211-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,1 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84211-63:
(7*8)+(6*4)+(5*2)+(4*1)+(3*1)+(2*6)+(1*3)=112
112 % 10 = 2
So 84211-63-2 is a valid CAS Registry Number.
