218967-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218967-39-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,9,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 218967-39:
(8*2)+(7*1)+(6*8)+(5*9)+(4*6)+(3*7)+(2*3)+(1*9)=176
176 % 10 = 6
So 218967-39-6 is a valid CAS Registry Number.
