263716-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263716-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,1 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 263716-56:
(8*2)+(7*6)+(6*3)+(5*7)+(4*1)+(3*6)+(2*5)+(1*6)=149
149 % 10 = 9
So 263716-56-9 is a valid CAS Registry Number.
