119751-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119751-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,7,5 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 119751-15:
(8*1)+(7*1)+(6*9)+(5*7)+(4*5)+(3*1)+(2*1)+(1*5)=134
134 % 10 = 4
So 119751-15-4 is a valid CAS Registry Number.
