94223-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94223-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,2 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 94223-87:
(7*9)+(6*4)+(5*2)+(4*2)+(3*3)+(2*8)+(1*7)=137
137 % 10 = 7
So 94223-87-7 is a valid CAS Registry Number.
