881309-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 881309-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,3,0 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 881309-47:
(8*8)+(7*8)+(6*1)+(5*3)+(4*0)+(3*9)+(2*4)+(1*7)=183
183 % 10 = 3
So 881309-47-3 is a valid CAS Registry Number.
