1159629-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159629-49-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,6,2 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1159629-49:
(9*1)+(8*1)+(7*5)+(6*9)+(5*6)+(4*2)+(3*9)+(2*4)+(1*9)=188
188 % 10 = 8
So 1159629-49-8 is a valid CAS Registry Number.
