83456-22-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83456-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,5 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83456-22:
(7*8)+(6*3)+(5*4)+(4*5)+(3*6)+(2*2)+(1*2)=138
138 % 10 = 8
