216983-42-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216983-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,9,8 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 216983-42:
(8*2)+(7*1)+(6*6)+(5*9)+(4*8)+(3*3)+(2*4)+(1*2)=155
155 % 10 = 5
So 216983-42-5 is a valid CAS Registry Number.
