1008756-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1008756-40-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,8,7,5 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1008756-40:
(9*1)+(8*0)+(7*0)+(6*8)+(5*7)+(4*5)+(3*6)+(2*4)+(1*0)=138
138 % 10 = 8
So 1008756-40-8 is a valid CAS Registry Number.
