17605-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17605-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,0 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17605-87:
(7*1)+(6*7)+(5*6)+(4*0)+(3*5)+(2*8)+(1*7)=117
117 % 10 = 7
So 17605-87-7 is a valid CAS Registry Number.
