87726-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87726-57-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,2 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87726-57:
(7*8)+(6*7)+(5*7)+(4*2)+(3*6)+(2*5)+(1*7)=176
176 % 10 = 6
So 87726-57-6 is a valid CAS Registry Number.
