158611-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158611-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,1 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158611-20:
(8*1)+(7*5)+(6*8)+(5*6)+(4*1)+(3*1)+(2*2)+(1*0)=132
132 % 10 = 2
So 158611-20-2 is a valid CAS Registry Number.
