1159629-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1159629-50-1 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, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1159629-50:
(9*1)+(8*1)+(7*5)+(6*9)+(5*6)+(4*2)+(3*9)+(2*5)+(1*0)=181
181 % 10 = 1
So 1159629-50-1 is a valid CAS Registry Number.
