1292783-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1292783-82-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,7,8 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1292783-82:
(9*1)+(8*2)+(7*9)+(6*2)+(5*7)+(4*8)+(3*3)+(2*8)+(1*2)=194
194 % 10 = 4
So 1292783-82-4 is a valid CAS Registry Number.
