1219683-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1219683-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,6,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1219683-40:
(9*1)+(8*2)+(7*1)+(6*9)+(5*6)+(4*8)+(3*3)+(2*4)+(1*0)=165
165 % 10 = 5
So 1219683-40-5 is a valid CAS Registry Number.
