201667-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 201667-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,6,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 201667-39:
(8*2)+(7*0)+(6*1)+(5*6)+(4*6)+(3*7)+(2*3)+(1*9)=112
112 % 10 = 2
So 201667-39-2 is a valid CAS Registry Number.
