Check Digit Verification of cas no
The CAS Registry Mumber 271598-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,1,5,9 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 271598-87:
(8*2)+(7*7)+(6*1)+(5*5)+(4*9)+(3*8)+(2*8)+(1*7)=179
179 % 10 = 9
So 271598-87-9 is a valid CAS Registry Number.
