1158799-92-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1158799-92-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,8,7,9 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1158799-92:
(9*1)+(8*1)+(7*5)+(6*8)+(5*7)+(4*9)+(3*9)+(2*9)+(1*2)=218
218 % 10 = 8
So 1158799-92-8 is a valid CAS Registry Number.
