81099-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81099-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,9 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81099-74:
(7*8)+(6*1)+(5*0)+(4*9)+(3*9)+(2*7)+(1*4)=143
143 % 10 = 3
So 81099-74-3 is a valid CAS Registry Number.
