142177-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142177-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,7 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142177-61:
(8*1)+(7*4)+(6*2)+(5*1)+(4*7)+(3*7)+(2*6)+(1*1)=115
115 % 10 = 5
So 142177-61-5 is a valid CAS Registry Number.
