749255-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 749255-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,2,5 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 749255-87:
(8*7)+(7*4)+(6*9)+(5*2)+(4*5)+(3*5)+(2*8)+(1*7)=206
206 % 10 = 6
So 749255-87-6 is a valid CAS Registry Number.
