Check Digit Verification of cas no
The CAS Registry Mumber 202715-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,7,1 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 202715-99:
(8*2)+(7*0)+(6*2)+(5*7)+(4*1)+(3*5)+(2*9)+(1*9)=109
109 % 10 = 9
So 202715-99-9 is a valid CAS Registry Number.
