87747-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87747-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87747-17:
(7*8)+(6*7)+(5*7)+(4*4)+(3*7)+(2*1)+(1*7)=179
179 % 10 = 9
So 87747-17-9 is a valid CAS Registry Number.
