847740-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 847740-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,7,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 847740-33:
(8*8)+(7*4)+(6*7)+(5*7)+(4*4)+(3*0)+(2*3)+(1*3)=194
194 % 10 = 4
So 847740-33-4 is a valid CAS Registry Number.
