190523-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190523-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,5,2 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 190523-70:
(8*1)+(7*9)+(6*0)+(5*5)+(4*2)+(3*3)+(2*7)+(1*0)=127
127 % 10 = 7
So 190523-70-7 is a valid CAS Registry Number.
