99278-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99278-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,7 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99278-47:
(7*9)+(6*9)+(5*2)+(4*7)+(3*8)+(2*4)+(1*7)=194
194 % 10 = 4
