218787-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 218787-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,7,8 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 218787-38:
(8*2)+(7*1)+(6*8)+(5*7)+(4*8)+(3*7)+(2*3)+(1*8)=173
173 % 10 = 3
So 218787-38-3 is a valid CAS Registry Number.
