436803-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 436803-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,6,8,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 436803-67:
(8*4)+(7*3)+(6*6)+(5*8)+(4*0)+(3*3)+(2*6)+(1*7)=157
157 % 10 = 7
So 436803-67-7 is a valid CAS Registry Number.
