81159-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81159-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81159-61:
(7*8)+(6*1)+(5*1)+(4*5)+(3*9)+(2*6)+(1*1)=127
127 % 10 = 7
So 81159-61-7 is a valid CAS Registry Number.
