191660-35-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 191660-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,6 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 191660-35:
(8*1)+(7*9)+(6*1)+(5*6)+(4*6)+(3*0)+(2*3)+(1*5)=142
142 % 10 = 2
So 191660-35-2 is a valid CAS Registry Number.
