Check Digit Verification of cas no
The CAS Registry Mumber 202476-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,4,7 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202476-26:
(8*2)+(7*0)+(6*2)+(5*4)+(4*7)+(3*6)+(2*2)+(1*6)=104
104 % 10 = 4
So 202476-26-4 is a valid CAS Registry Number.
