155751-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155751-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,7,5 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155751-20:
(8*1)+(7*5)+(6*5)+(5*7)+(4*5)+(3*1)+(2*2)+(1*0)=135
135 % 10 = 5
So 155751-20-5 is a valid CAS Registry Number.
