Check Digit Verification of cas no
The CAS Registry Mumber 201226-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,2,2 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201226-88:
(8*2)+(7*0)+(6*1)+(5*2)+(4*2)+(3*6)+(2*8)+(1*8)=82
82 % 10 = 2
So 201226-88-2 is a valid CAS Registry Number.
