Check Digit Verification of cas no

The CAS Registry Mumber 1026748-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,7,4 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1026748-40:
(9*1)+(8*0)+(7*2)+(6*6)+(5*7)+(4*4)+(3*8)+(2*4)+(1*0)=142
142 % 10 = 2
So 1026748-40-2 is a valid CAS Registry Number.

Application of bis(iminophosphorane) in heterocyclic synthesis: New entries to symmetrically or unsymmetrically substituted thieno[2,3-d:5,4-d′] dipyrimidine-4,5(3H,6H)-diones

Ding, Ming-Wu,Xu, Sheng-Zhen,Zhao, Jun-Feng

, p. 8366 - 8371 (2007/10/03)

The bis(carbodiimides) 4, obtained from bis-aza-Wittig reactions of bis(iminophosphorane) 3 with 2 equiv of aromatic isocyanates, were reacted with secondary amine to give symmetrically substituted 2,7-diaminothieno[2,3-d:5,4- d′]dipyrimidine-4,5(3H,6H)-d
