810691-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 810691-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,0,6,9 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 810691-81:
(8*8)+(7*1)+(6*0)+(5*6)+(4*9)+(3*1)+(2*8)+(1*1)=157
157 % 10 = 7
So 810691-81-7 is a valid CAS Registry Number.
