Check Digit Verification of cas no
The CAS Registry Mumber 202605-61-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,6,0 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 202605-61:
(8*2)+(7*0)+(6*2)+(5*6)+(4*0)+(3*5)+(2*6)+(1*1)=86
86 % 10 = 6
So 202605-61-6 is a valid CAS Registry Number.
