827319-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 827319-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,7,3,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 827319-22:
(8*8)+(7*2)+(6*7)+(5*3)+(4*1)+(3*9)+(2*2)+(1*2)=172
172 % 10 = 2
So 827319-22-2 is a valid CAS Registry Number.
