1639785-80-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1639785-80-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,7,8 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1639785-80:
(9*1)+(8*6)+(7*3)+(6*9)+(5*7)+(4*8)+(3*5)+(2*8)+(1*0)=230
230 % 10 = 0
So 1639785-80-0 is a valid CAS Registry Number.
