81113-07-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81113-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,1 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81113-07:
(7*8)+(6*1)+(5*1)+(4*1)+(3*3)+(2*0)+(1*7)=87
87 % 10 = 7
So 81113-07-7 is a valid CAS Registry Number.
