81836-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81836-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,3 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81836-89:
(7*8)+(6*1)+(5*8)+(4*3)+(3*6)+(2*8)+(1*9)=157
157 % 10 = 7
So 81836-89-7 is a valid CAS Registry Number.
