190778-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 190778-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,7,7 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 190778-70:
(8*1)+(7*9)+(6*0)+(5*7)+(4*7)+(3*8)+(2*7)+(1*0)=172
172 % 10 = 2
So 190778-70-2 is a valid CAS Registry Number.
