195977-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195977-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,9,7 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195977-70:
(8*1)+(7*9)+(6*5)+(5*9)+(4*7)+(3*7)+(2*7)+(1*0)=209
209 % 10 = 9
So 195977-70-9 is a valid CAS Registry Number.
