119252-56-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119252-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,2,5 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119252-56:
(8*1)+(7*1)+(6*9)+(5*2)+(4*5)+(3*2)+(2*5)+(1*6)=121
121 % 10 = 1
So 119252-56-1 is a valid CAS Registry Number.
