4883-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4883-86-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4883-86:
(6*4)+(5*8)+(4*8)+(3*3)+(2*8)+(1*6)=127
127 % 10 = 7
So 4883-86-7 is a valid CAS Registry Number.
