693784-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 693784-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,3,7,8 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 693784-52:
(8*6)+(7*9)+(6*3)+(5*7)+(4*8)+(3*4)+(2*5)+(1*2)=220
220 % 10 = 0
So 693784-52-0 is a valid CAS Registry Number.
