195977-51-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195977-51-6 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, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 195977-51:
(8*1)+(7*9)+(6*5)+(5*9)+(4*7)+(3*7)+(2*5)+(1*1)=206
206 % 10 = 6
So 195977-51-6 is a valid CAS Registry Number.
