1393818-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1393818-71-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,8,1 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1393818-71:
(9*1)+(8*3)+(7*9)+(6*3)+(5*8)+(4*1)+(3*8)+(2*7)+(1*1)=197
197 % 10 = 7
So 1393818-71-7 is a valid CAS Registry Number.
