1019107-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1019107-90-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,1,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1019107-90:
(9*1)+(8*0)+(7*1)+(6*9)+(5*1)+(4*0)+(3*7)+(2*9)+(1*0)=114
114 % 10 = 4
So 1019107-90-4 is a valid CAS Registry Number.
