119872-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119872-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119872-40:
(8*1)+(7*1)+(6*9)+(5*8)+(4*7)+(3*2)+(2*4)+(1*0)=151
151 % 10 = 1
So 119872-40-1 is a valid CAS Registry Number.
