839685-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 839685-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,6,8 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 839685-22:
(8*8)+(7*3)+(6*9)+(5*6)+(4*8)+(3*5)+(2*2)+(1*2)=222
222 % 10 = 2
So 839685-22-2 is a valid CAS Registry Number.
