1620568-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1620568-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,5,6 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1620568-74:
(9*1)+(8*6)+(7*2)+(6*0)+(5*5)+(4*6)+(3*8)+(2*7)+(1*4)=162
162 % 10 = 2
So 1620568-74-2 is a valid CAS Registry Number.
