88104-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88104-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,0 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 88104-56:
(7*8)+(6*8)+(5*1)+(4*0)+(3*4)+(2*5)+(1*6)=137
137 % 10 = 7
So 88104-56-7 is a valid CAS Registry Number.
